Adams is not a "point of attack" type guy. He makes a living by chasing people down. He doesn't have enough sand in the bucket to hold up against pulling guards and motion tight ends. He is not even close to being in the same stratosphere as Kam Chancellor with respect to taking on blockers at the point of attack. Like I said, he is a pursuit guy.
Here is what will happen, and the opposing quarterbacks will rehearse it the week leading up to the game. Every. Single. Time.
1) Pre snap read to see which side Adams is lined up at.
2) Check into a play to run directly at Adams because running AT him will totally neutralize his effectiveness as a pursuit guy.
3) Put a tight end in motion from the strong side to specifically find the "Will" linebacker (Adams) or conversely pull a guard to serve the same purpose.
If light, fast, undersized guys could routinely deploy as a Will linebacker, the league would be chock full of them and even if it was routinely done, they would be highly specialized in defensive packages intended for use on predictable passing downs only. A player intended to defeat pass blockers, not run blockers. In other words, a highly specialized player, with very little diversity, that is devouring a significant portion of the salary cap.
"Luxury", rotational players are not typically among the highest paid players on a NFL team. Adams can be a blitzing terror. Thats about it. Used as a safety, Adams couldn't find the ball if it stuck in his face mask. HE FLAT OUT SUCKS in coverage.
