Most deserving of being extremely entitled: Alabama. They honestly expect to win the NC every year. Runner up: USC. They are a "fire the coach after every loss"-type of program
Most entitled without even the slightest bit of reason to be entitled: South Carolina. Truly, a preposterous level of expectation for such a mediocre program. They have a big stadium. That's it. Very poor bowl record and few bowl appearances overall. Runners up: Cal, a rougher and more demanding fan base than you'd expect for a team that recruits very well and does nothing.
Most entitled for having done very little on the national stage in awhile (in other words, the most obnoxious): Tennessee--only two national titles in their program's history, but their fans act they've won 20. Runners up: Michigan
Least entitled: Great programs, slightly more realistic expectations, extremely loyal fan bases: Oklahoma (lots of second places, but nobody really wants Stoops gone), Georgia (think Tennessee would have kept Richt that long?), Texas A+M (rain or shine their fans are great).
Programs quickly becoming the most insufferable because of their recent success: Auburn, Ohio State, Notre Dame
Programs faded (or fading) into irrelevance that were once national powers: Virginia Tech, Nebraska, Colorado, Washington, Texas, Miami
