That said, when I met with Redskins coach Mike Shanahan in December, he mentioned Cooley's injury as one of the bad turning points for the Redskins in 2011 and spoke of how much he liked being able to "set the perimeter" on offense with two very good tight ends. So my belief is that he'd like to have Cooley back.
