‘The Buffalo Bills lost four starters, including future Hall of Famer Bruce Smith, off the NFL’s top-ranked defense of a year ago. That defense has fallen all the way to third-best in the league after two games. New York Jets coach Al Groh, whose team faces that defense on Sunday, said Wednesday that the Bills are ”just as tough as before, only faster. They are very aggressive, very physical and very speedy. They are not weak in any one area defensively – they have one of the best lines, one of the best groups of linebackers and one of the best defensive backfields. It’s a very cohesive operation, and they have a complementary defense.”’
