Anytime a line with this much money on it jumps 2pts past a key number just before game day, you know the house is exposed and looking to balance, big time. Whether its an enormous number of public bettors or a few big players, you know what the house is looking to do with that sort of a move.
A move to 9-9.5 would indicate they were fishing for Auburn bets, but clearly here they are looking to balance.
