Centers: John Sullivan (MIN) and Will Montgomery (WAS)

Brian De La Puente is making a late run for one of these spots, but he’s got some work to do to catch both Sullivan and Montgomery. A special word for Sullivan who has been so good over the past two years you could make a case that he’s the best center in the league.
I really did not see Montgomery as a Probowl center but then again i have not really paid attention to other teams to see how he ranked. I know he has been pretty good for us and i have been happy with him. but i guess other people think he is one of the best.

On another note this guy also doesnt rank Williams as a probowl LT and i sure do. Right now i dont think i would trade him for anyone else. He also has RG3 in the probowl which is awesome.
