Because expectations were so high for the Bills’ Mike Williams, the fourth overall pick of the 2002 draft, he has been perceived as a mild disappointment. Though Williams has been inconsistent, he has flashed dominance. Last season, for instance, he handled Jevon Kearse of the Titans. Williams has continued to get better, and his improvement should be accelerated this season. Playing next to him will be a rock in right guard Chris Villarrial, and coaching Williams will be Jim McNally, one of the best in the league.
