If someone has a personal connection to a college team, it is really great to follow them.
Cheering for a pro team (any sport) in the words of an old writer Bernie Lincicome, "cheering for a pro team is just cheering for laundry".
Unfortunately, that distinction is now utterly obliterated, and every player in college is playing on a 1-year contract with impending unrestricted free agent status -- so it's even worse than any professional sport. At least in professional leagues, teams can sometimes hold on to a draft pick for half a decade, or sign a player to a long-term deal and get a few seasons out of them before they demand a trade.
