Just a hunch I have that Bennett will bag the most. Partly because... as an offense, who do you block, who do you double, how do you protect? And I think Bennett will be the hustling opportunist who gets not just his own sacks, but also a few extra "cleanup" sacks caused by the pressure from others. I see Irvin having a good year and continuing to grow, and Avril making a monster contribution as well, and the two of them flushing panicked QB's straight into the waiting arms of... Bennett; with Scruggs and Mebane each getting a couple extra that way too. I have no idea what contribution Jaye Howard will make, and where Pete and John are on getting big body inside rush DT's, keeping Alan Branch, using Red Bryant inside, etc. I don't see Clemons back in game shape and contributing until the second half of the season.
Bennett - 11
Irvin - 10
Avril - 9.5
Clemons - 4 (all in 2nd half of season)
Scruggs - 4
Mebane - 3
Howard - 4
Wagner -4
Wright - 3
Bryant - 2
I think our D benefits a lot from improvements in our O. Some of my posts way back chided Pete for not coming into games earlier in the season with a game plan of "Russell, score early and often" instead of the "Russell, don't lose it for us" game plans of the first 3/4ths of the season. In 2013, the training wheels are off, and the offense scores early and often. Teams find themselves having to throw to try to catch up, creating many more pass rush situations and thus sacks, not to mention INT's. I think someone mentioned a 50/25 Sack/Int goal for the defense.
