Celtics shaky once again on road in playoffs

CLEVELAND — The Celtics were loose, smiling and laughing. They weren’t straining to hear each other speak and there were no obnoxious Cleveland fans heckling them.

All was quiet as Boston worked out Sunday.

Practice isn’t an issue on the road in the postseason. Playing games is the problem.

Less than 24 hours after a 30-point bludgeoning at the hands of LeBron James and the Cavaliers in Game 3 of the Eastern Conference finals, the Celtics did some film study and critical evaluation.

They were hard on them- selves.

“I thought it was embarrassing,” Celtics guard Jaylen Brown said of Boston’s 116-86 loss — and his own performance. “I thought we came out, the way I played, the way I performed, how not aggressive I was in the first half, I look at that as fuel to come out in Game 4 and be excited about it and be ready to play and ready to fight.”

Brown scored just 10 points — 13 below his average after two games in the series — and was in almost immediate foul trouble as the Cavs dominated while pulling within 2-1 in the series.

Celtics coach Brad Stevens may change his lineup change for Monday’s Game 4, perhaps re- turning to center Aaron Baynes and bringing Marcus Morris off the bench. Stevens has to do something to free up Al Horford, who has been held in check by Cleveland’s Tristan Thompson the past two games.

By starting Baynes, Stevens could force Cavs coach Tyronn Lue to make a counter move and either put Kevin Love — or even James — on Horford.

Stevens wouldn’t tip his hand. Beyond any lineup tweaks, more concerning for him may be his team’s Jekyll-and-Hyde postseason play.

The Celtics have been sensational at home, going 9-0. But the road has been treacherous as
