Thing is that the Pats are, quite obviously, attempting to move toward a starting set of corners that excel in press man to man coverage. Dennard fits that mold. Cole looked like he fits that mold. Talib obviously fits that mold. McCourty doesn't quite fit that mold. They'll go with Talib, Dennard, and Cole (more than likely) and keep McCourty at safety where, against the pass, he's better than Chung and gets to keep his head turned toward the play. Gregory and Wilson will duke it out for the last safety position.
