Bobick transferred from BYU to Oklahoma State, where Sutton coached. That game was at the Delta Center (now Vivint) in 2011 I believe. I was there. The booing was loud and it was incredibly classless and embarrassing for BYU fans to do that to one of our former players who had given a lot to our program. I remember hanging my head in shame and telling people around me to pipe down.

Found an old post from CB where another poster describes that shameful moment. The BYU AD at the time even issued an apology and a reminder for BYU fans to be good sports. Link:
