Because it's not about one game or one season. It's about hopefully working towards winning a championship. I was significantly less frustrated with this team several years ago because Dame was younger and the team seemed to be in a better position to continue to grow.... but we have stagnated. Hell, the least stressful seasons are the ones where you know you're shit, but you have young players that are developing and a decent pick after the season. It's easy to forgive poor play and enjoy watching guys develop when you're clearly building towards something.
This team is no closer to winning a championship now than they were three or four years ago, meanwhile we're pissing away Dame's prime and we're continuing to hang our hopes on the foundation of Dame/CJ/Stotts. And how is that going to change? Fire Stotts? Trade CJ? Convince another star player to sign for the minimum? We're cemented in this rut until someone gives.
So yes, winning a game is great. I like to win. Winning is fun. And I like to watch Dame do what Dame does, but it's still bitter sweet because we know this team won't go far in the playoffs and there's really no clear hope for the future. Just the same thing over and over.
