"One benefit of the Celtics bench is its emotion. That emotion also can be its downfall, however.

Little wonder that in the process of making the big plays in last night's 96-89 Game 4 win against the Lakers at the Garden, Nate Robinson and Rasheed Wallace each picked up a technical foul.

It was Wallace's sixth of the playoffs, and one more means a league-mandated one-game suspension.

"Unfortunately, that's probably our most emotional group when you have Nate, Rasheed and Tony (Allen) on the floor at the same time," coach Doc Rivers said. "So the techs happen. That's the only thing we didn't like. We have a no-fourth-quarter-tech rule, which was blown out of the water today. But other than that I thought our energy was absolutely terrific."

Wallace was whistled for a technical after arguing a foul on Kobe Bryant midway through the fourth quarter."
