3 (and none of this is relevant if they lose to Auburn). And Tennessee is 5-5 and could well make it 4. Which is probably the same number utah will have if they run the table — they are currently at 3.
On the loss side of the ledger, Bama lost to #1 LSU. utah lost to unranked USC.
And did I mention that Auburn already beat Oregon, and that Alabama is already ranked ahead of both utah and Oregon?
