I pose this question because it seemed to me as if Tyson was less effective as the season went on. I don't have an exact number of snaps he played but I thought he was on the field an awful lot. He started the season well by getting a sack in the first game of the season against Denver, but ended the season with only 3.5 sacks. By no means am I complaining about his contribution, because I think he played well. He continually got better against the run and even demanded double teams on passing plays, which proved he was getting mentioned in defensive coordinators gameplan before playing the Jaguars. But I can't help but believe D'Anthony's presence would've been beneficial to Tyson and the entire defense as a unit. The biggest concern for me was how Tyson was on the injured list through the week later in the season most weeks, although he ended up playing in those games. 

Tyson isn't the only one that needs depth behind him, as does Terrance. Douzable has been serviceable, but no one would disagree to say that an upgrade wouldn't be nice. Gene Smith said that no other positions than the defensive lines, DE and DT, work off of rotation. With that being said, defensive end is fine as far as depth goes, now we just need another nose tackle type of DT in the mold of Terrance. Acquire that, coupled with the return of D'Anthony and the Jags could have one of the best young defensive line rotations in the league. Even though the secondary is still going to need an infusion of new talent, finishing the d-line would make it less of a glaring weakness, because there were times when we still didn't get pressure on the QB.
