Williams may play defensive end at times following the loss of Darnell Dockett (knee) for the season, the Cardinals' official site reports. "I played it a little bit last year toward the end of the season, trying to spell Calais and Dockett for a few reps," Williams said. "I'm definitely going to do anything the coaches ask me." Williams has been injured at times during his four-year career yet still averaged 31.3 tackles in 13.5 games per season. If he's rushing the quarterback away from his customary spot at nose tackle, there's a high likelihood that he adds to his meager sack total of one to date. However, even with additional responsibilities, his IDP prospects won't approach that of line mates Calais Campbell and Dockett's replacement Frostee Rucker.
