Dude, you're a broken record. Get new material, or at least go do some research so you don't sound so stupid. It's embarrasing!
Sure, Gruden knows the Raiders, but THEY - and more importantly, their coaching staff - know Gruden! Callahan was a disciple of Gruden's and is employing a VARIATION of the system that Gruden put in place 4 years ago. That doesn't mean Gruden can magically predict what the Raiders will do. Duh.
If anything, there IS no advantage, simply because the Raiders have far too much talent on offense to be stopped. Just because you *know* Gannon is going to throw the ball to Rice, or Brown, or Garner, or Porter, or Jolley, doesn't mean you know when or how. Or that you can stop it. Learn something about the game before you post again, k? Thx!
