After getting blown out by Philadelphia on Wednesday, the Celtics  needed some momentum heading into their eight-game road trip. Fortunately, the Trail Blazers were in town and they brought their considerable baggage to the floor with them.
It was uncomfortable watching a team so completely unravel, but the Celtics weren’t complaining after taking a 35-point halftime lead in a 104-86. Portland had 16 turnovers in the first half, forced only two and watched time and again as various Celtics flew down the lane for layups and dunks.
The Celtics will start an eight-game road trip in Los Angeles against the Lakers on Sunday.
WHAT WENT RIGHT
Not settling: It wasn’t clear immediately that the Blazers were in full ship be sinking mode, but the Celtics didn’t waste any time finding out. Rajon Rondo  and Pierce attacked the rim right from the start and once they realized Portland wasn’t going to put up a fight, it was open season on the basket.
Sasha Pavlovic  has the cure for the second quarter blues: The veteran swingman hit a 3 on the team’s first possession and then got fouled on a breakaway layup. Pavlovic scored eight points in the quarter and the Celtics scored 18 of the first 20 points. It was 45-19 after six minutes and 38-13 for the quarter.
Save those legs: Kevin Garnett made all five of his shots and played just 20 minutes. Allen, Pierce and Rondo clocked in with just 26 apiece. They needed that.
Bench production: Avery Bradley  scored 10 points and had five assists. Greg Stiemsma  missed all nine shots he took, but he had seven rebounds, three steals and two blocks. Pavlovic added 10 points and it was the bench’s best performance in weeks, even without Mickael Pietrus  (knee) and Chris Wilcox  (personal reasons).
WHAT WENT WRONG
Injuries, again: Pietrus has struggled with his shot lately, but coach Doc Rivers  revealed before the game that his problems are related to a knee injury. Pietrus tried to play through it on Wednesday against Philly and Rivers acknowledged before Friday’s game that he would have liked to have had that back. The hope is that Pietrus will be available for Sunday’s game against the Lakers, but that’s far from given.
