ESPN announcers say fans' perceptions of bias are typical

If you’re a fan of the Miami Heat or Dallas Mavericks and start believing over the next two weeks that ABC’s broadcast crew of Mike Breen, Jeff Van Gundy and Mark Jackson is rooting against your team, you’re probably not alone.
You’re also wrong, according to the announcers, who say they hear complaints about their alleged favoritism all the time.

Breen and Jackson were responding to questions from an Oklahoma City reporter, who implied Thunder fans believed the broadcast team was pulling for the Mavs during the Western Conference finals.
“There's no way in the world that we have anything against the Oklahoma City Thunder,” Jackson said.
“... Our job is to speak the facts. The facts are that a couple of games in the series there were breakdowns, and they didn't play as well as they could have played. They had a couple of games won, and they did not win them. But they had a great season, and they should be extremely proud.”
