The Clippers were licking their wounds Sunday after falling apart down the stretch and losing 96-88 to the Portland Trail Blazers in Game 3 of their first-round playoff series Saturday at Moda Center in Portland. The Clippers lead the series 2-1 with Game 4 on Monday night back at Moda Center.

The Clippers led 85-81 with 3:52 to play and scored only three more points while giving up 15.

The Clippers held a lengthy film session at their hotel Sunday. Blake Griffin appeared rather bummed out after emerging from it.

“It was a pretty awful film session,” he said. “It wasn’t even the last two minutes, it was throughout the entire game. You know, really from the beginning, we let them get comfortable. We let them, like I said last night, do what they wanted to do and they executed, to their credit. They did what they wanted to do and we just … I thought we were careless and didn’t execute, didn’t move the ball from side to side. We didn’t do the things that made us successful in those first couple of games.”

The Clippers won Games 1 and 2 by respective scores of 115-95 and 102-81 at Staples Center.
