BOSTON — Let the gamesmanship continue.

Celtics coach Doc Rivers shifted into his best Phil Jackson mode yesterday when he complained about the officiating in the NBA Finals. He accused Game 3 Laker star Derek Fisher of “flopping” and said that he sent in a videotape to the league showing what he claimed were offensive fouls for which they Lakers weren’t called.

“I thought there was a lot of holding going on and a lot of flopping going on,” Rivers said. “I just think it was a ton of moving screens they got away with.”

Rivers said the Celtics, who have been in foul trouble throughout the Finals, are largely to blame for their “discipline defensively,” but he feels the Lakers are getting away with too much, particularly illegal screens.

“We got called for one, and I don’t think the Lakers got called for any moving picks last night,” Rivers said. “I don’t send in a lot [of film] usually to the league. I sent in a lot this morning.”
