With only 1 win and a split you don't qualify as one of the greats IMHO. You can argue the split but that's a stretch considering football has always been plagued by the vagaries of the system. The hard truth has always been you need to win out to control your own destiny and even that's not always enough. If we go back and consider all of the polling crimes of the past we'd have no time for politics...or anything else for that matter. At the time while I felt SC was robbed but I wasn't prepared to take it away from Oklahoma and in the end LSU should have recieved their due. Bad luck for SC but the primary claim to that championship is LSU. The split was a cop out.
After what USC did to OU in that game, there is no way you can ever convince anyone that LSU would have beat USC. Hell, even LSU knows that.
