Here's how I see the SEC:
Tier 1:
Auburn Stands alone.
Tier 2:
Ole Miss, MSU, Bama
Tier 3:
LSU, Texas A&M, Arkansas
I don't think any of those third tier teams are incapable of beating anyone they play. I think there's a lot of parity in the west.
FWIW, I think the entire East is below the West's Tier 3. If I had to keep going with the entire SEC, it would be:
Tier 4:
Georgia, Missouri
Now begins the awful teams that I would give a 0.00% chance of beating anyone in the entire West.
Tier 5:
South Carolina, Florida, Kentucky
Tier 6:
Tennessee
Tier 7:
Vanderbilt
I think the only SEC team Tennessee beats is Vandy, but it's enough of a gap to put them both in tiers to themselves.
