Every team they have left is currently ranked, they play the #1 team twice, and the average AP ranking of their remaining opponents is 9.7. No one else is even close.
Auburn probably has the second hardest remaining schedule, given they play Alabama twice, Kentucky, Ole Miss, and TaM. So 3 top 10 matchups and 2 top 20.
TaM has 4 games left against ranked teams (1, 3, 5, and 22).
Ole Miss also has the same 4 games left against ranked teams (1, 3, 5, and 22).
LSU has 5 ranked teams left to play (3, 5, 8, 15, and 22).
Vandy also has 5 games against ranked opponents but fewer on the high end (5, 8, 15, 19, and 21). To be fair, they did just lose to #1 in their last game so that's a brutal stretch.
Oklahoma has 5 ranked matchups as well but even more on the lower end (3, 15, 19, 21, 22).
Arkansas has 4 ranked matchups left (1, 8, 21, and 22).
By comparison 4 of our remaining games are against unranked teams, though we do have to play #1 and #2. No one else in the SEC plays more than 3 ranked teams
Texas has the easiest remaining schedule in the SEC, with their only ranked matchups being against us (15) and Miss State (22).
