Hey but according to Gailey we have the "principle pieces", hmmm, NT? Bills head coach Chan Gailey appearing on 103.3 FM The Edge in Buffalo Friday afternoon said he believes they have some of the principle pieces needed to field a capable 3-4 defensive front. His concern lies with the depth at some positions. "We have some of the right people to play the defense," said Gailey. "Our depth is cause for concern at this point. We’ve got to make sure that we have depth at certain positions. But we think we can adapt to the 3-4 with some pretty good people right off the bat." One position that obviously going to need some added depth is linebacker, first from the simple fact that you need more of them to field a 3-4 defense. Most 3-4 teams carry eight and sometimes nine linebackers.
