I'd say there are like 15 teams, with 3 a cut above the rest....
The triumvirate:
Bama
OSU
Georgia
those 3 run shit right now, basically land whoever they want in recruiting, have sustained high level success for the past decade and a half.
Blue Bloods:
Michigan
Notre Dame
USC
Texas
Oklahoma
Helmets:
LSU
Penn State
Florida State
Florida
Tennessee
Clemson
Oregon
Nebraska used to be on this list, think they might've lost their spot. Miami was on this list too, but they've fallen off the map too. Clemson and Oregon probably took those spots.
