Has no one ever, in the history of all time, played man coverage on the outside in a base 4-3 defense? I'm assuming not, just judging from the comments around here lately.
Do we all really believe that an NFL defensive coordinator wouldnt have the intelligence to utilize the strengths of his players, regardless of the defensive look? Hell, if no ones ever played press man with his 4-3 corners, I'd say the situation in Dallas is one ripe for innovation.
We could call it the Dallas-two.
