I'll cheer for BYU, no matter how bad they are. I'll donate to Cougar Club, and travel to a few games per year...even if the team sucks. Does that make me a bad fan?
I'll root for the team to win each game, even if it means the coach will still be the coach for another year. Does that make me a bad fan?
I choose to be optimistic about the next game, or the next season. Does that make me a bad fan?
I believe the best way for a fan to help the team is to cheer for them, and hope they win games. I don't think a good fan hopes the team completely implodes and everything burns to the ground, just so it'll be an easy decision for the administration to get a new coach. I'd rather the team we have now rights the ship and starts winning. Does that make me a bad fan?
