JKJoe,
With respect to the fumble, I think the replay clearly showed that the player's knee was down before the ball came loose. It was very close and part of the reason it was hard to tell is that the same knee popped up so quickly, one replay angle made it look as though it never hit the ground.
One other thing, the ball only popped loose as a result of his own hand (the one in which the ball was being held) hitting the ground - I always thought that the ground could not cause a fumble - I know that this is the case in the pros regardless of whether a knee was down or not, but maybe not the case in college fb.
