I have DirecTV, which may not be available in Phoenix (?). You get only one feed per game (with some very rare exceptions), so yes, you have to listen the other team's announcers about half the time. I think you usually get the road feed.
To answer Joe Mama's questions:
What do you like about it?
Almost everything.
What don't you like about it?
1. The pay-per-view movies generally suck. There might be one good one, and then all the rest got lousy reviews or didn't even earn major releases. You can pay a monthly fee for HBO and Cinemax and those things, but the "Direct Ticket" pay-per-view films are pretty useless.
2. There's a really annoying "information icon" that pops up on the screen from time to time. I've never figured out how to make it go away. Basically, it's an invitation (if you click the right button on your remote) to get a sales pitch about something. Like we don't get enough advertisements on TV. Just get the damn icon out of my face.
Does the picture "jump" or "Skip"?
Almost never. I might get this problem once or twice a year, and I watch a fair amount.
Of course, sometimes the channel's broadcast screws up, as happened with ESPN during the Suns-Pistons (?) game a few days ago. But that's not the dish system's fault.
