Wt: 346   Strengths: Elite size and strength. Impressive upper body strength allows him to knock smaller pass rushers off their course with ease. Has the lower body strength to anchor against bull rushers. Decent athleticism for his size; could be viewed as a right tackle prospect by some teams. Quick feet for his size. A nasty run blocker who has the ability to swallow up defenders. Gets to the second level quicker than most interior linemen. Experience at both guard and tackle; started at left tackle throughout senior year. Weaknesses: Occasionally struggles with speed rushers off the edge; just doesn’t have the mobility to match their explosiveness off the snap. Stamina may be a slight issue; appears to wear down throughout the course of the game and will get sloppy with his fundamentals, playing too high at times. Comments: Glenn was put in a tough position switching to left tackle prior to his senior year. He was surprisingly effective, but lacks the athleticism to play the position in the NFL. Most teams will view him as a guard, where he has the potential to be among the best in the game. Some more run-oriented teams may view him as a right tackle. As a guard or right tackle he is definitely a 1st-round prospect, and should be able to play at a high level from day one. Videos: 2011 vs LSU

The most popular choice seems to be Alabama’s Courtney Upshaw, who played a hybrid linebacker/end role for the Crimson Tide.

Upshaw has 1st-round talent, but would be a reach in the top 10.

While I certainly understand the logic behind the Upshaw/Bills connection, I don’t think he’s a great fit in Buffalo.

As much as I like Upshaw, he shouldn’t be in the top 10 of any draft board belonging to a team which runs the 4-3 defense. He can be an effective pass rusher in that system, but he struggles against the run. He simply lacks the strength to consistently shed blocks, especially when he’s lined up at the point of attack.

That’s not to say he can’t start at defensive end at the next level, but the Bills could get much better value at No. 10. As a defensive end, Upshaw compares favorably to a guy like Jabaal Sheard. He a solid pass rusher, and holds his own in the run game, but not someone you want to build your defensive line around.

If the Bills are committed to improving their defensive line in this draft, their best strategy may be to trade down. This isn’t a great class of ends at the top, but there are up to seven prospects who could warrant mid-to-late 1st round picks. The Bills could potentially slide back a few slots and still land a guy like Nick Perry or Melvin Ingram, both of whom fit into the 4-3 scheme better than Upshaw.

Regardless of what you think of Tebow, he deserves to be recognized for his clutch performances. At times it seemed like he truly did will the Broncos to victory. In terms of team success, he exceeded all expectations.

But the fact remains that the Broncos scored two or fewer touchdowns in five of their seven victories with Tebow as the starter. And when you win games like that, it is never the quarterback’s doing.

The real MVP in Denver was the defense, which allowed 13 points or fewer in five of Tebow’s 11 starts – four of which resulted in wins that were unfairly credited to the Tebow by the media.

It’s tough to evaluate Tebow given his unorthodox style of play, but by using ESPN’s Total QBR we can reasonably compare him to more traditional pocket passers. Total QBR grades a quarterback’s performance in a given situation, and rewards players who make positive plays in clutch moments – regardless of whether the play is a run or pass.

One might expect this formula to favor Tebow more than the traditional statistics. However, of 34 qualifying quarterbacks, Tebow ranked 32nd – ahead of only Curtis Painter and Blaine Gabbert.

Tebow’s Total QBR of 27.2 is something awful (50 is considered average), but what makes it worse is his inconsistency.

Using each quarterback’s single-game QBRs, compared to their season-ending QBR we can determine who was most consistent – and Tebow ranks among the worst. On average, Tebow’s performance was anywhere for 23.8 points above or below his Total QBR.

One could argue that this shows his ability to perform at a high level, but 23.8 points above his average still only gets him to a Total QBR of 51 – roughly the league average.

A further examination of Tebow’s QBR also shows us that, contrary to popular belief, the Broncos did not live and die by his performance.

When Tebow performed above the 50-point mark, the Broncos were just 2-2 (incuding a 41-23 beat down at the hands of the Patriots). On the flip side, when Tebow performed below league-average, the Broncos were 5-3 (including an 18-15 win over the Bears despite a QBR of 16.5).

In sort, the Broncos won despite Tebow, but because of him.

So where do the Broncos go from here?

It’s tough to know exactly what the Broncos front office will look for in a quarterback, which makes predicting Tebow’s potential successor difficult. GM Brian Xanders technically drafted Tebow, but in reality it was Josh McDaniels calling the shots. Now, it’s safe to assume that John Elway will have the final say over the quarterback situation, with John Fox’s opinion factoring into the mix as well.

If we assume Elway will be attracted to quarterbacks who most closely resemble himself, two guys in this year’s draft class come to mind:

Nick Foles, Arizona – While he probably isn’t the next Elway, Foles does share some physical trails with the Hall of Famer. Like Elway, Foles is an impressive athlete for his size. He’s confident throwing on the run and will occasionally take off down the field. His biggest issue has been consistency, but could be an option in the late 2nd or 3rd round.

Brock Osweiler, Arizona – We’ve never seen a quarterback with Osweiler’s size and athleticism, but he is extremely raw – which just might make him perfect for the Broncos in the 3rd or 4th round. Elway could draft Osweiler and honestly tell the Denver fan base that he is not a threat to Tebow. This would appease the fans for the time being, while the Broncos can take their time grooming Osweiler for the future. If Tebow continues to develop, no problem – trade Osweiler. If Tebow fails, no problem – start Osweiler. It’s a win-win situation.

Alex Dunlap of the Austin Chronicle caught up with Ryan at the Senior Bowl, and asked the Cowboys defensive coordinator who he was focused on: “I’m only looking at DBs. Nothing else. DBs.”

Dunlap went on to say that Ryan has a particular interest in Leonard Johnson, a cornerback from Iowa State who could be an option in the 2nd or 3rd round.

It’s tough to say just how much say Ryan has in the Cowboys draft plans, but if he’s this blunt about their needs to the media, it’s safe to assume he’s going to be hounding Jerry Jones over the next few months about the issue.

The problem the Cowboys have, however, is that they may be stuck in no-mans land in the 1st round if they hope to address their secondary at that point. Dre Kirkpatrick [scouting report] would be an obvious target, but could be off the board by pick No. 14. There are a number of potential late 1st-round cornerback prospects, but anyone other than Kirkpatrick or Morris Claiborne would be a significant reach unless the Cowboys were to trade back.

There is one other name to keep on eye on, however: Janoris Jenkins [scouting report]. Based purely on talent, Jenkins is a top-15 prosect and would be a great fit in Dallas’ secondary. But most teams will drop him, or completely remove him, from their draft boards due to character issues.

Jerry Jones has shown a willingness to consider troubled-but-talented prospects in the past. He recently drafted Dez Bryant in the 1st round, when many others had dismissed him for off-field issues. And he’s made similar moves in free agency (Pacman Jones, Terrell Owens, etc).

Following the season, Harbaugh spoke about the issues at receiver and lamented the failure of Braylon Edwards. He stated “we were looking for that big stature receiver” when acquiring Edwards, but due to injuries and ineffectiveness he was released midseason.

Fortunately for the Niners, there are a number of “big stature” receivers who should come off the board in the first few rounds. Here are

Michael Floyd, Notre Dame [scouting report] – There’s a good chance Floyd will be off the board by the time the 49ers are on the clock, but if they’re serious about addressing this concern they may consider trading up. Aside from Justin Blackmon, Floyd is the most well-rounded receiver in this year’s class.

Alshon Jeffery, South Carolina [scouting report] – Jeffery’s stock has fallen dramatically this season, but could still be an option in the late 1st round for the 49ers. His inconsistent play may scare some teams off, but he has the skill set to make an immediate impact in the red zone which is what the 49ers really need.

Dwight Jones, North Carolina [scouting report] - Like Jeffery, Jones has some issues with consistency, but at 6’4″ he could be a relatively cheap option for them in the late 2nd round. He won’t challenge Michael Crabtree for the role of No. 1 receiver any time soon, but if they’re primarily interested in a red-zone threat, Jones could be a good fit.

All I do is run routes. When you don’t get that many opportunities, it’s hard to talk… Half the time you’re not going to be open. That’s why they call you a playmaker – just give you chances.

Crabtree is in no position to complain about his role.

Clearly Crabtree views himself as a “playmaker” – a title which few others would bestow upon him at this point in his career.

But despite his somewhat disappointing career, there’s no denying that the fact that he is the 49ers No. 1 receiver. And they’ve treated him as such. In 2011, Crabtree was targeted 107 times, 24th most among receivers, and more than any of his teammates (even Vernon Davis, who was thrown at 92 times).

Not only is Crabtree the Niners top receiver, but he’s essentially their only weapon at the position. Nearly half the balls Alex Smith threw to his wide receivers were aimed at Crabtree – a higher percentage than all but four others in 2011.

The question now is: can Jim Harbaugh control Crabtree, or will he become a distraction?

The Niners already attempted to bring in some competition for Crabtree by signing Braylon Edwards last offseason, which failed to work out due to injuries and ineffective play. And they’re likely to either sign or draft a receiver this year as well.

Even if Crabtree remains their No. 1 receiver, he’s all but guaranteed to see a reduced role in 2012. How will his ego react to that?

These are questions which are certainly being discussed behind closed doors in San Francisco, which could lead the team to seriously consider a 1st-round receiver – and possibly could lead them to trade up to ensure they land someone capable of replacing Crabtree in the near future.

Wt: 265   Strengths: Prototypical build for a pass-rushing end; tall with long, strong arms. Explosive off the snap; consistently beats offensive tackles off the edge. Strong wrap-up tackler who can also deliver the big hit. Does a nice job keeping his eyes on the backfield; good all-around awareness on the field. An intense player who plays with an impressive motor. Has some experience dropping into zone coverage. NFL bloodlines; older brother Arthur plays for Ravens. Top intangibles; coaches speak very highly of his leadership skills. Intelligent on and off the field. Weaknesses: Struggles to shed blocks against the run; has the frame to add some weight, which would help him against more powerful offensive linemen. Needs to develop an array of pass rush moves; too reliant on pure speed and athleticism at this stage in his career. Missed five games with an undisclosed knee injury in 2011. Comments: Jones would have benefited from returning to school, as he still needs to get stronger against the run, but should still draw interest from teams as early as the late 1st-round based on his potential. He has the size, strength and athleticism of a prototypical left defensive end in the 4-3 scheme, and could develop into an elite three-down lineman. Some 3-4 teams may also view him as a candidate to shift to outside linebacker, where he could make an immediate impact as a pure pass rusher. Had Jones returned to school and improved upon his weaknesses, he potentially could have climbed into the top-10 discussion. As a result, someone could wind up with a steal in the late 1st or 2nd round. Videos: 2011 vs West Virginia 

Josh Norman – CB – Coastal Carolina
Norman concluded the season as a relative unknown, having not been tested against top competition, and was expected to be a late-round prospect. However, he shined at the Shrine Game and impressed scouts so much that he earned a late invite to the Senior Bowl. He now looks like a top-100 lock, and could climb as high as the 2nd round.

Alfonzo Dennard – CB – Nebraska
For those that watched Dennard closely this season, his stock probably didn’t change much. But the Senior Bowl served notice to everyone that he just doesn’t have the athleticism or the technique to be considered an elite prospect. There has even been some talk of him moving to free safety in the pros. He rode the momentum of his junior year – when he played opposite Prince Amukamara – as long as he could, but we’ve now seen the real Dennard.

Bobby Wagner – OLB – Utah State
Wagner was already a solid 3rd or 4th-round prospect heading into the Senior Bowl, but may have risen into the early 2nd round with his performance. Aside from his relatively short stature, he’s the complete package. Wagner also benefits from this being a relatively weak class of linebackers. Scouts were impressed with his athleticism, and also with his play on special teams.

Dwight Jones – WR – North Carolina
The knock on Jones, which has become a theme for the Butch Davis-era Tar Heel prospects, is that he lacks effort and concentration. He drops too many balls, and isn’t always a crisp route runner. These issues are magnified due to his relative lack of speed.

Vinny Curry – DE/LB – Marshall
The all-star games are always most important for the small-school prospects, and Curry took advantage of his opportunity to play with the big boys. His best moment came in the one-on-one drills when he had little issue beating Mike Adams off the edge with his speed rush. He definitely displayed the athleticism necessary to play standing up in a 3-4 defense.

Kellen Moore – QB – Boise State
Moore was hoping to establish himself as the next Colt McCoy this offseason, as an undersized but accurate signal caller. Unfortunately, Moore simply doesn’t have an NFL arm. There were even reports of CFL scouts saying they weren’t interested in Moore because they need quarterbacks who can whip the ball through the windy conditions they sometimes face.

The hiring of Chuck Pagano from the Ravens means the Colts defensive philosophy will change, as Pagano has already stated he is bringing Baltimore’s hybrid 3-4/4-3 defense with him.

While this does mean changes will be coming, it might not be as drastic a change as you may assume. For starters, over the past few years the Ravens have actually lined up in a base 4-3 defense more often than their 3-4. Assuming Pagano sticks with this strategy, Dwight Freeney and Robert Mathis (assuming he’s re-signed) won’t need to make significant adjustments.

What the Colts do need, however, is a true nose tackle for those instances where they line up in a standard 3-4. Antonio Johnson could probably fill that role if absolutely necessary, but he isn’t a true space-eater like Pagano had in Baltimore with Terrence Cody

Obviously the Colts won’t be addressing this need in the 1st round, but there are a few options for them in round two or three:

1. Dontai Poe, Memphis – As the consensus top-rated nose tackle, there’s a decent chance Poe comes off the board in the 1st round. If he does slide to the 2nd round, however, he should be high on the Colts draft board.

2. Josh Chapman, Alabama – Chapman would be a slight reach at the top of round two, but would be a nice fit in Indianapolis. He has experience in the 3-4 defense at Alabama, which would make his transition to the NFL fairly easy.

3. Alameda Ta’amu, Washington – Ta’amu is more likely to be an option for the Colts in the 3rd round. He’s limited athletically, and more of a true space-eater who won’t be a three-down lineman at the next level.
