LSU is a football factory in Baton Rouge—a university with 30,000 undergrads in a city that is 1000% behind their football program and athletic department.
Some of y'all bring this upon yourselves, if you're really expecting the University of Miami—a liberal university with 11,000 undergrads, in a diverse metropolitan city—to behave and operate like an SEC powerhouse football factory.
Their alum also writes big checks. Georgia just dropped $200,000,000 into their program; the "Do More" campaign to get them closer to Alabama's success. Most of that came from alumni dollars; their fans practicing what they preach. (Welcome to the perils of being a program where most of the fan base aren't alum. Alumni write checks to their alma mater; the average fan doesn't.)
Miami fans don't even go to games and silently protest while still wearing 10-year old Nike gear, despite UM switching to adidas 6-7 years ago.
Hardly an apples to apples comparison. You get what you pay for—and Miami fans don't write checks, so neither does UM's admin.
