Coach Chan Gailey says the Bills will still use multiple defensive fronts despite their official switch to a 4-3 scheme. "When we hand you a lineup card, it's going to have two defensive tackles, two defensive ends, and three linebackers," Gailey said. "But how much we end up in even spacing (or) odd spacing ... that's determined by players and the offense we're playing." The Bills will mix in some 3-4, but new DC Dave Wannstedt has only ever coached 4-3s. Finding 4-3 players will be a priority in the draft.
