I didn't say I was happy with the team. I just choose to continue supporting the team. I'll still spend money on them, and I won't cheer for them to lose.
I think the team will improve faster if it has supportive fans and $. Withholding support and $ will just make it harder for the administration to attract better coaches and players.
If you want to doom the program to mediocrity forever, then go ahead and make sure they have less resources to work with. And make sure recruits know that if they don't meet expectations, you'll stop watching the games. That'll help.
