That's still not simple, a lot of assumptions in that post.
The 1998 Dallas Cowboys went 10-6 with Troy, Emmitt and Irvin still all there. They had NO ONE to line up opposite Irvin. With Moss, who we now know is one of the greatest to play the game at his position, we would have most certainly beaten the Cardinals in the playoffs.
As far as the Campo/Parcells years, Quincy Carter, Vinny Testaverde, Drew Bledsoe, and yes, Tony Romo would have all benefitted greatly from having Randy Moss to throw to.
I'm sorry, but I refuse to take the position that everything that could have gone wrong with Moss would have if he came here. He would have helped this team and his QBs far more than he would have harmed them.
