As long as I've been watching basketball my 2 favourite teams were the Spurs and Raptors. So when the Raptors suck I just watch the Spurs. I'm also big on football (NY Giants, Seahawks) and Hockey (Kings, Blackhawks, Leafs, Flyers). Just find something else to occupy your time when the Raptors are sucking.
I pretty much just follow the teams moves and see how they pan out. If good, hey I can watch more Raptor stuff and enjoy it, if bad I'll just watch something else when I can't take how much they suck anymore.
