However it's easy to overlook Dvoracek due to his injury problems, but it's not easy to overlook his production. Dvoracek is a classic run plugger at the DT spot who also has the ability to stretch plays down the line of scrimmage. This enables the linebackers to swoop in and make a play leading to the Bears being a dominant run defensive team.
The Bears' defense led the league in stuffed runs in 2008 and that was primarily due to the guys up front. Led by Dvoracek the Bears ranked fifth overall in the league in stuffing the run. It's no coincidence that the Vikings, Titans, Steelers Eagles and Bears all have that run stuffing tackle in the middle of it all. All were amongst the six leaders in rushing defense in 2008.
Dvoracek is a stout plug who uses his leverage well and his hands well to be successful against the run. While Dvoracek may not be THE big mammoth DT that Bears fans wish were still around, he plays like one. Dvoracek is good at the point of attack and it is so often overlooked his value to the team when he is in the game.
The question is can he stay healthy for a full season and be a starter on the defensive line? Does he deserve to be on the roster if he can't stay healthy? The answer in my opinion is yes he still deserves to be on the D-Line as a starter. Sure Anthony Adams has been productive, but he has always been more fresh when he comes into the game. Adams is also more of a three-technique type of DT rather than a hole filler. Adams isn't all that big either so can he hold up for an entire season as a starter?
What about Marcus Harrison? How far into the doghouse is he with his weight problems? Is he in shape to be ready to play a full 16 game slate? How long until he is in a position where he won't be overly winded from pounding the middle of the defense.
Never mind that Harrison is more a pass rush three-technique specialist as well, thus leaving the run defense vulnerable with him in the game.
So hopefully for the run defense's sake the Bears can find a spot for Dust Dvoracek on the roster, and keep him. He is just the type of double team commanding run stuffer that keeps the Bears defense in a position to be dominant.
