Of course Cousins is going to say that, he is busy kissing Gruden's ass, who was not the one who drafted RGIII, and who is looking for a QB more like Dalton to command, and can win.
Cousins needs to start right away kissing that behind, work his tail off, do exactly what Gruden says at all times, so Gruden will go to bat for him when RGIII is ready to come back and play.
Smart marketing move for Cousins towards his head coach.
