The Tampa Bay Buccaneers may have to sit their starting running back Carnell ?Cadillac? Williams this Sunday against the Jets as Williams nurses a sore left foot and hamstring injury. "In a way, yeah [it would be better to sit out Sunday]," Williams told the paper. "One thing I've got to understand is it's a long season; it's not like college. "In college you're halfway through the season right now. But here, we ain't even halfway through yet. So that [sitting out the game] might be a good idea. But we're still evaluating things with the trainer."
