The only two complaints I really have about this game, one of them is just nit-picky, are out of King's hands.
The first is the fact that everytime your quarterback is hit, no matter how far into his delivery or how hard, the ball just wobbles and floats for a few seconds to some random spot along the line, usually to be intercepted. In real life, a quarterback being hit while throwing will have a bad throw, but it will a) head in the general direction of its target b) usually be thrown low or into the ground and c) definitely not do what happens in the NCAA.
My second complaint, and as I said it's not necessarily a "complaint" but something I just noticed while watching the Saints-Vikings game tonight and something EA could do to make the game more realistic, is about fumble recoveries. When there is a fumble, the first person to the ball always recovers it without a problem and usually without even having to dive on it. In real life, someone who tries to just scoop up the ball almost always at least bobbles it.
