Saints running back Reggie Bush admits that his recent rift with USC has been hard to accept. With that said, he's trying to put it all behind him as New Orleans prepares to defend their Super Bowl crown. "I like to think that I'm pretty mentally tough and I never allow any outside distraction to affect me on the football field," Bush said Saturday. "Once I step on the field, it's all football. I try to remember that every time I step on this field. "This is kind of like our sanctuary. This is where we get a chance to kind of forget about everything and play football, do what we love to do and not worry about anything else." Bush had previously addressed the situation in June after the NCAA announced it found violations involving Bush and hit USC with sanctions. "I think I'd be lying if I said it didn't," Bush said when asked if it bothered him. "Obviously, it does, but at the end of the day it is what it is. All I can really do now is focus on the New Orleans Saints and just try to move on. It bothers me and it sucks. The whole situation is terrible and nobody feels worse about it than I do."
