BOSTON -- Just as LeBron James nixed his pregame powder toss for the playoffs, so too did he remove himself from social media.

James hasn’t posted on his Twitter account since April 27. In his final tweet before the playoffs, he thanked his fans, did a little self-promotion and then stepped away from the 140-character media circus.

“It’s not playoff silence,” James said. “My fans, I’m still with them. But I haven’t been on.”

It’s just another way James has limited the noise around him during the most important postseason of his career. James has about 4.5 million followers on Twitter and, needless to say, they’re not all well-wishers.

James’ self-imposed social media blackout is one of several changes he has made during the playoffs. In addition to cutting out his popular pregame chalk toss, James has also removed himself from pregame introductions altogether.

During the Eastern Conference finals, James has remained in the locker room during player introductions and then joined the team on the court just before tipoff. Instead of warming up on the court, James usually rides a stationary bike behind the scenes to prepare for games.

Then there is James’ reading kick. For the first time since he was in high school, James began reading books during the playoffs. He’s on his sixth book in five weeks.

BOSH in game 5?

Chris Bosh missed his ninth consecutive game Sunday with an abdominal strain, but there’s a chance he could be activated for Game 5 in Miami. Bosh has been rehabbing on the court for a week and just recently rejoined the team during shootarounds and practices.

On Sunday, Heat coach Erik Spoelstra said Bosh was still out indefinitely.

CHESS MATCH

In every playoff series, opposing coaches match wits and try to find weaknesses in their opponents. As series evolve, the strategies and adjustments evolve as well. Although Spoelstra wasn’t too fond of Pacers coach Frank Vogel’s methods, the Heat’s coach has long been an admirer of Boston coach Doc Rivers.

“I have incredible respect for Doc,” Spoelstra said. “He’s a great coach, and I’ve had some opportunity to spend a little bit of time with him during the summers.

“He’s a great X’s and O’s guy, but I think what really separates him is his ability to manage personalities. That’s the part I was really interested in.”

Much has been made about Rivers’ adjustments since Game 2. The Celtics limited Dwyane Wade with a double team in Game 3 while also getting Kevin Garnett more involved offensively. Spoelstra scoffed at the idea that a series subplot about how he counters Rivers’ moves draws any interest from fans.

“I don’t think people are paying any amount of money to see that matchup,” Spoelstra said.
