Wash coached the defensive line that led the team with 21.5 of the total 28 sacks the Bucs racked up in 2009, showing that his front is very dominate and controls the entire defense. The Bucs defensive line is the anchor for the entire team, so Wash has to push his players to work harder, putting more pressure on them to produce and come up with big plays. With the rest of the defense very young as well, they are dependent on the front 4 to control the pace of the game and constantly pressure the quarterback, which helps the rest of the defense.
Walsh has depth and talent on the line this year, but it is very young. McCoy and Price come into the mix as well and the pressure will be on their shoulders to anchor and come up big for the entire unit this year. Along with Roy Miller and some experienced defensive linemen (very little experience, but veterans considering the Bucs roster), the Bucs have a good mixture on the line and will be called upon again to anchor and lead the way on defense.
