Sometimes I just don't get some of the fans. I really don't.
Fans want to be associated with winning and being the best. It's affirming for them, it bolsters their ego and sense of self-worth. And most people want to be in groups. Whether we consciously realize it or not. Tennessee athletics is one such group.
When a player or team does poorly, so poorly that the team is viewed as "bad," fans can and will try to distance themselves psychologically from those people. You've met the type, right? They're all "rah rah" and "Go Vols" when it's easy and Tennessee is winning, but when Tennessee struggled or was irrelevant, those people turn hostile or switch to attacking or trashing the program and the people involved with it. It's an act, more for the self than it is for other people. "I don't cheer for losers." Because only suckers would cheer for losers, right? So they create distance, in their own mind, to try to feel better about being a fan of the team, and to disassociate from the losing. This isn't unique to Tennessee. Fans do it across all of sports. We've all met that guy, or girl, who turns into a real hater when the chips are down.
So in Guarantano's case, due to the team's poor results and Guarantano's struggles, you're going to run into Tennessee fans who want to belittle or insult him whenever he's brougth up. Derision. Scorn. Cast out the unclean. Etc, etc. He was the QB, so he's a poster child for "bad Tennessee." And some people really can't let it go.
For the record, Guarantao put up with a lot of BS and while he made poor decisions he went out there and kept fighting. Did that play suck? A thousand percent. I don't get it, to this day. But the guy's A-okay in my book.
