well he didnt "always suck" at right tackle.maybe big mike isnt a elite right tackle ,but when healthy he does play right tackle pretty ok.his expierment at left guard was with a week of practice and he was still hurt.just because mike shouldn't have been a 4th pick in the draft does not mean he cannot be useful on our line.if mike williams leaves buffalo i bet he turns into a good football player.now if he is evaulated fairly and the new coaches determine that they cannot use him ,well then that is a different story.
