Yes, you cannot pass on a player this talented.
No, he is too big of a risk.
Soul, forgive me for not tagging the post where you mentioned the lack of depth at DT. I lost my place and never could find it. But I'm still going to comment on it.
Right now, we have a three man rotation at defensive tackle, which was essentially what we used last season since Paea went largely untouched until the first Vikings game. Paea is looking more and more like he's going to be both a pass rusher and a run stopper because in the short time that he was active last season, he produced two sacks. He's an absolute beast, and along with Melton, our sack total should remain high from the three technique and NT positions.
To be totally honest, I'm a little shocked that Peppers didn't get at least two to three more sacks last year, but the idea that the thin depth at the position caused him exhaustion and the fact that he battled a bum knee off and on throughout the season probably played a huge role in his "lack of production."
