I'm hardly a Wendell apologist but... Let's be fair. He is one tough SOB, better than any of his competitors in down field run blocking, so far. He seems very able to get out and find the LB on pulls and traps, to spring runners both between the tackles and on wide runs. Plus he calls a good line blocking game.
Like in the passing game, he can have troubles moving a big and good DT when even great technique is not enough. It is merely a question of size. He is undersized. If he were 30 lbs heavier, he would be an AllPro Center. But he is not.
Wendell can play and win in this League and frequently does. Thankfully for him there are only so many Wilforks, Harlottis and Suhs (and Knightons) available, and there are not enough to go around around for all the teams. Even Superman had his Kryptonite; and Wendell has these mammoth guys to rag doll him unfortunately.
The hard-nose, tough guy is still someone I'd want on my Team, even if not as a starter.
