One thing seems clear -- the Bills need not just one but TWO good NT's for their 3-4 defense. Big guys wear down quickly and, like everyone else, get injured at times, so the Bills will have to add both a starter and a back-up
It seems to me that one possible way to meet this rather daunting challenge is to trade for Red Bryant of the Seattle Seahawks. Bryant, who is 6-5 and 320 lbs., was drafted in the fourth round two years ago, but has been inactive most of his NFL career due to the fact that he doesn't fit well into Seattle's 4-3 scheme. He does not have the ability to penetrate the way a 3-gap DT is supposed to do, and is sitting behind two DT's who are well-suited for a 4-3. But the fact is that he is a big, strong run-stuffer. When he was in the line-up at Texas A&M, his team had just about the best run defense in the NCAA; when he went out with an injury they became one of the worst. He clearly made an enormous difference. No one questions the fact that he is very powerful and can push back the pocket, making it easier for DE's and rush OLB's to do their jobs. He is also very athletic, having run a 4.9 40 at the combine. If you check our sister website, Fieldgulls.com, you will see that a number of folks there keep calling for the coaches to play Bryant anyway even though he is miscast for the scheme because they suspect he is very talented, although some have given up on him and think it is time for the Hawks to unload him.
My guess is that he wouldn't cost that much. Perhaps we could swap Chris Kelsay for him (yes, I'm trying to make Kurupt's day) or Roscoe Parrish (that would be trading a flea for an elephant). We could even throw in one of our two sixth-rounders if necessary. At a minimum I suspect that Bryant could make a solid back-up NT for us, and as Chan Gailey has said depth on the front seven is a high priority. But it's also possible that he could blossom in a real 3-4 defense and become a starter. How he would work out is of course impossible to predict, and we need two NT's anyway, so it would be imperative to add another in the draft (perhaps Cam Thomas?) and let that rookie and Bryant compete with each other. If we did that, and found ourselves a good pass-rushing OLB, we would be well on our way to rebuilding our defense along the lines Gailey wants to go.
