I picked up the NBA iPhone app for $9 so I can listen to every game. I have more time to listen than watch so it isn't too big a problem for me. It is really nice to have some homers talking about the game instead of listening to national guys or the local Portland clowns I get when that game comes around (not since the playoffs a long time ago).
By the way, Portland has been in this Comcast boat for about 6 years now. it doesn't get any better. DirecTV and Dish probably won't be carrying them.
