The Bills are going to continue to play a hybrid defense. Nix, Wannstadt and Gailey all downplayed a switch back to the 4-3, saying that every team in the league except for KC and Detroit plays some level of hybrid. Also, if they flat switch to a 4-3 what are they going to do with all their 3-4 players (Merriman, Edwards, Carrington, Sheppard, Moats, Batten, etc.). Kick them to the curb and fall another 2 years behind in the perpetual rebuild? Upshaw would be a player that can play 4-3 or 3-4 so he would be a logical pick, but this is all premature. Players move up and down like crazy after the combine.
