If you watch the end of the Redsk*ns game, on the crucial down when Newman picks off the pass... where is the coaching staff "hiding" Roy?
Here's a hint, because I've watched that play several times. He's one-on-one with Cooley, absolutely blanketing him. Campbell looks his way immediately... Cooley is obviously his first option. Because of Roy's coverage, he has to look to the other side and ends up throwing the pick to T New.
That's the kind of play that Roy NEVER gets credit for, but it's a crucial play nonetheless.
You don't notice it, but I guarantee you that the coaches do. That's why, when the game is on the line, Roy is still on the field.
