I think the Cotton has fallen off the most. I think it gets grandfathered in a bit, but whatever year it went SEC vs Big 12 low seeds, it was down a peg or two. I know it's in the CFP now, but for me, its reputationally not back to where it was.

What year did the Fiesta pass it? Has it passed it back?

On non-CFP seasons, the Cotton seems kind of like a dumping ground with Western Michigan and Memphis having played in it the past few years.
