If his side wasn’t hurting so badly, Chris Bosh would have destroyed the Heat’s locker room out of frustration the night his abdominal muscle decided to give out.

Emotionally, Bosh said he “went into a rage” after being injured in Game 1 against the Indiana Pacers in the 2012 Eastern Conference semifinals. Physically, he needed assistance to stand up from a chair.

On Wednesday, Bosh gets another chance to prove himself against center Roy Hibbert and the Pacers when the Heat begins its best-of-7 series with Indiana in the Eastern Conference finals. The Heat’s big man wouldn’t want to be playing anyone else for a chance to reach The Finals.

“I’m going to have to have a big match up with Roy,” Bosh said. “I feel he is the X factor for them. I’m the X factor for this team. This is going to be, I think, the matchup that really turns the series.”

Off the court, Bosh has been talking about his matchup against Hibbert for days — one of the best offensive centers in the game versus one of the best interior defenders.

“I was talking with my family about it the other night,” Bosh said. “To be able to have a chance to compete against [Indiana]. … I didn’t get the chance last time. I felt last time I really could have made an imprint on the series, and it’s funny how things come back around. I’m going to be get another shot.”

Bosh unabashedly considers himself the X factor in the series, but there are other dynamics to the Heat’s frontcourt that make this series against Indiana completely different than the one the Heat struggled through last year to win in six games. In addition to Bosh, the Heat features Chris “Birdman” Andersen coming off the bench, Udonis Haslem is an entrenched starter, and Shane Battier, who started against the Pacers in 2012, is back in a reserve role where he can provide a strategic offensive mismatch against Indiana’s big men — David West, in particular.

Birdman, Battier, and Bosh are the Heat’s “Killer B’s” against the Pacers’ blue-collar approach.

“Our bigs have to be big in this series,” Heat coach Erik Spoelstra said.
