I don't know how you watch those games and think he's not a 2nd rounder.
He's brutalizing the offensive linemen he faces. He's getting off blocks. He's staying rooted against the double teams. When linemen go on the attack against him, they can't move him. And when he goes on the attack, most times in pass rush, you'll see two sets of eyes on him, lots of double-teaming. And if he's not doubled, the QB is on an egg timer, and uncomfortable because the pocket is collapsing. For the kind of player he is, his ability to get lateral and cut off the ball trying to escape the perimeter, or to turn around and chase the ball into the second level, is phenomenal.
The scheme fit is also superb.
I agree with some of what you said and i did like a fair amount of tape i saw......minus the LSU tape where i felt Damien Lewis got the better of him time and time again (a guard still on the board in R3). That said, the downward trend of production and questions about maturity seemed to sour some on his overall ranking and draft value. So as was the case with Hunt, i felt we could have had him later.
I saw this quote on him:
Davis said at the NFL combine, “There were a lot of things I wasn’t doing to improve my game. I wasn’t really focused enough sometimes.” If Saban and Bama can't get guys to focus, will they focus once in the league with money in their pockets? There's risk in that.
You shift Hunt to 56, Davis to 70 and take a high talent player at 39......or trade back (as was reported for Miami at 39), pick up some additional ammo to move around, then i start to see an elite draft class with exceptional value. Instead i see a good draft class that sets a base but left opportunities on the table.
The talent still on the boards at 39/56: Shenault/Mims, Taylor/Dobbins/Akers/Dillon, Blacklock/Elliott, Delpit/Winfield/Ashtyn Davis/Chinn, Uche/Baun, Cleveland/Lewis/Jones. I'm sure i'm missing others but those immediately come to mind.
You do run the risk of losing those guys but you also have ammo to jump back up with 4th/5th round picks in your pockets if you feel a team ahead may take them.
If you wait too long and lose Hunt, you still have Damien Lewis available. If you wait too long on Davis, you have Hamilton, Elliott, Gallimore on the board as well as many of the centers still out there at a position of need. Plus there's a few true nose tackles later in Fotu, Peninsini, Roy.
