Beating LSU in their stadium at any time in the past decade is impressive. They don't lose there often. In fact, under Miles (which has been since 2005, I think), they have only lost like 4 times at home.
So, yeah, Bama beating LSU at LSU would be, in my opinion, a whole lot more impressive that Oregon beating Utah. I have to side with ESPN and the resident Bammer on this one.
