You're more likely to get a 2nd Big 12 team with 2 losses or a 3rd ACC team than any of the current 3 loss SEC teams. The only curveball being if A&M beats Texas and Georgia in the championship, you might get A&M and Georgia in with 3 losses and Texas and Tennessee in with 2.
Ole Miss just so happens to be playing the 2nd worst power 4 football team in the country this week (thank God for Purdue.) If they win by 60 it still wouldn't impress anyone on the committee enough to leapfrog a 3 loss Texas, Alabama, or Georgia if they lose in the SEC Championship game.
