"2. LeCharles Bentley, C, New Orleans
Bentley has good size at 6'2, 313, but it better known for his quickness. Quick footwork gets him out of his stance, and out blocking linebackers when necessary. His is lithe and swift off the snap, and is the rare center who can get out and pull. For all of his size, he does tend to get pushed around by very physical nose tackles, as his slight lack of lower body strength keeps him from maintaining position against a fierce bull rush. However, Bentley is tenacious and fiesty, and will not give up even when he appears to be overmatched. He is smart and consistent, and makes good adjustments at the line. Only 26, Bentley is better when he can get out and move, unblocked, and would fit best with a team that can surround him with Pro Bowl caliber players."
I've never watched Bentley play before, but if this description is accurate, the guy sounds like a small improvement over Johnson. They both have the same strengths and weaknesses.
