With the Buffalo Bills taking defensive tackle Marcell Dareus third overall Thursday the team has has a pair of versatile defensive lineman that can play multiple positions.
In other words the pair present a bunch of problems for teams.
With versatile lineman that can play either the 3-4 or 4-3 you can expect head coach Chan Gailey and assistant head coach and inside linebackers coach Dave Wannstedt to have the pair shift and move all over the line of scrimmage. That means you can expect the Bills to shift their alignment right before a snap like many offenses do. In other words the defense could be in a 3-4 look and then immediately shift into a 4-3 look.
Also, you can expect the pair, along with fellow defensive lineman Torell Troup and Dwan Edwards to flip flop positions. In other words on one down Williams may be at defensive end with Dareus over the nose and Edwards at the other end position, then on the next down Edwards could be over the nose with Williams and Dareus at the end positions. This would especially be the case of the three were Williams, Dareus and Troup as all three could play any position.
In the end, even the New England Patriots are going to start having nightmares on how to block the Bills defensive line.
Doing that will screw up a lot of offenses, because even if the offense is prepared for it if the defense shifts right before a snap the offense will then have to either burn a timeout or stick with a bad play. If a team sticks with a bad play they run the risk of a defender coming in cleanly due to a lack of communication, especially on a pass play.
