This was a desperation pick by the Minnesota Vikings. Harrison Smith is not a 1st-round prospect, and only comes off the board here because of the significant dropoff in talent at safety once he’s off the board. And while safety was definitely a need, the Vikings had more crucial holes to fill.
I also don’t like to see teams like the Vikings trade up. When you’re in full rebuilding mode, there’s no reason to trade up unless it’s for a difference maker at a critical position such as quarterback.
