As someone who has social media research as part of his job... caring about follower counts is insanity.
For starters, the majority of followers are bots and spam, not real people. Next, brands buy followers constantly. Next next, many of these schools have athletic department accounts that dwarf their football-specific accounts, like SU. Lastly, even the top of the list, FSU's 54K followers, is ridiculously tiny. This an argument about who's largest amoeba.
