Cody is a decent option if we go 3-4, but as a 4-3 DT he is no where near as good as Suh or McCoy. I just dont see the Bills drafting Cody top ten as a 2 down DT when there is likely to be at least one other 3 down, better 4-3 DT availible.
Either way the best defense is a good offense, and if our offense had an offensive line, they may be on the field more. Okung, Suh, McCoy, or a DE like Dunlop or Griffen.
