Yea, Jamal did not get into USC coming out of high school due to grades. Goose played two seasons for the Gamecocks, but thought it would be fun to not go to class and eventually failed out of school. None of these things were really USC's fault.
One situation that I heard about, however, where they dropped the ball was with Zach Prince. He did not get into USC, however the coaches never notified him and he did not find out until about May(I believe). He had to scramble to find a place to go to school, and he's now playing at CofC. They should have informed him that he may not get in and to look around.
