It had ebbs and flows, runs and counters, and even some blood spilled by Kevin Garnett  after he was gashed by Pau Gasol . The Celtics  and Lakers didn’t disappoint in their first game since the 2010 finals.
You can break this game down in a number if different ways, but in the end it came down to a simple proposition: Could Kobe Bryant  beat the Celtics by himself? Bryant erupted for 22 points in the first half and helped the Lakers recover from an early nine-point deficit. He dueled with Paul Pierce  throughout the third quarter and into the fourth, but late in the game the Celtics were finally able to contain Bryant and the Lakers had nothing else left.
They can say that this was just another game, but the Celtics proved something in their 109-96 win Sunday afternoon. They proved that this is a different team than the one that left Staples Center  without a championship. The rematch is only 11 days away at the Garden.
WHAT WENT RIGHT
Paul Pierce destroyed Ron Artest : The captain destroyed his antagonist from last year’s finals, scoring 32 points on just 18 shots and sending Artest to the bench in the fourth quarter. There was nothing Artest could do to contain Pierce, who had both his long-range and in-between game working.
The Celtics were overwhelming in the second half, but Pierce kept them in position throughout the game in what might have been his best performance of the season.
Defensive Rebounding: This is very simple. When the Celtics clean up on the boards, the Lakers can’t win. The Celtics were strong out of the gate, allowing the Lakers just one offensive rebound in the first quarter. When the game sped up in the second, Pau Gasol and Andrew Bynum  were able to get on the glass.
The Celtics held the fort in the second half and Garnett was a huge factor with 12 defensive rebounds. For all the talk about what a difference a healthy Kendrick Perkins  would have made in Game 7, the 2010-11 version of Garnett would have been even bigger.
The bench: Give Nate Robinson  credit. The guard has been much-maligned in recent weeks for his propensity for taking long pull-up jumpers in transition. But, that’s what he does. The Celtics rely on him to come off the bench and provide instant offense and that’s what he gave the Celtics, scoring 11 points in 14 minutes. Glen Davis  also had a strong game, outproducing Lamar Odom and making huge plays down the stretch.
WHAT WENT WRONG
Rajon Rondo  didn’t look right (for half): Either there’s something physically wrong with the Celtics point guard, or he’s just worn down from all the minutes he’s played this season. Either way, Rajon Rondo followed up his disastrous outing against Phoenix (more turnovers than assists) with another low-impact performance in the first half.
The Lakers defensive scheme against Rondo is well-known at this point. They drop Kobe Bryant off into the paint where he forces Rondo to shoot jumpers, while also using his length to disrupt his passing and driving lanes. Too often Rondo simply takes himself out the action.
In the second half Rondo completely changed course. He had six assists in the third quarter and became far more aggressive in the fourth when matched up against Steve Blake . Rondo had 15 of his 16 assists in the second half and played (finally) like Rondo.
Kobe did work: The Celtics generally don’t mind when a superstar opponent tries to take a game over on their own. Their feeling — whether it’s LeBron James , Dwight Howard  or Bryant — is that if one player is trying to beat them, that makes them much easier to defend. But when Bryant makes 8-of-11 shots and scores 22 points as he did in the first half, that’s simply too much. Bryant managed to keep it close, but even he can’t beat the Celtics by himself.
Foul trouble: The whistles started early as both Ray Allen  and Bryant had to check out in the first few minutes with two fouls. Not surprisingly, foul problems also plagued Shaquille O’Neal  who got his fifth early in the third quarter. That led Kendrick Perkins to play 25 minutes, his longest outing since returning from knee surgery.
