The last shot I saw of the play, it looked like a Denver lineman maybe had only an arm on it and if Cam had dove down with his body on it he easily could have taken it away from whoever had his arm on it. I may have seen it incorrectly however, IMO, at that point in the game, it was clear that if Denver recovered the fumble, they were SB champs. That was the play that basically ended Carolina's season-long journey for a championship. Therefore, even if a 300-pound lineman has pounced his entire body completely on top of it you still dive and go after the ball.
