Tennessee and Miami comparisons are complete garbage. Besides a delusional fanbase, they share nothing else in common.
Tennessee has a **** load of money to spend. Miami's problem was always being cheap.
Tennessee has a huge, rabid fanbase that can routinely fill a 100,000 seat stadium. Miami can't get 60,000 people to go to a game unless it's FSU.
Tennessee has to rely on recruiting nationally because the local talent is doo-doo. Miami can miss on the top local players and still have top 10 recruiting classes because there's just so many good local players.
They had a good thing going under Fulmer. Yeah they only have the one national title in recent history but they were consistently among the nation's better teams. They put a ton of dudes in the league and generated a ton of money. It's hard to blame them because you always want to be better but sometimes, you have to be realistic about where your program stands in the nation's hierarchy.
