MIAMI — As they head into Game 2, both the Celtics  and Heat feel that they didn’t play their best in the opener and while there will be strategic adjustments on both sides, the sense is that both teams simply want to play their game better.
“As poorly as we played and they didn’t necessary play terrific either, you can clearly say some of it was due to their defense,” Doc Rivers  said before the team’s shootaround. “It wasn’t just us being bad. There’s somebody out there making you be bad and they had a lot to do with it.”
On the Celtics to-do list are guard the 3-point line better, particularly James Jones  who made 5-of-7 from behind the arc and keep Miami off the free throw line. Offensively, Rivers felt his team rushed and put themselves in a bad position.
“They’ll respond,” Rivers said of his team. “We’re usually a pretty good team in execution and we just were not. I was just surprised how impatient we were offensively. When you become impatient that makes you easy to guard. I think we were very easy to guard.”
“We’ve tried to exercise our mental disciple to maintain our mental edge,” he said. “It’s two physical teams, two very good defensive teams. There will be times when both teams struggle to score. Whoever can say that consistently played their game will likely win the basketball game.”
As for the prospect of going down 2-0 in this series, something that has never happened in the Big 3 era, Kevin Garnett  said that the Celtics were not thinking that way.
“You take one game at a time,” Garnett said. “Each game you learn something from it and you try to apply what you’ve learned to the next game. Obviously [1-1] is always good but you go 0-2 against a great team it’s very hard.”
Expect both teams to be sharper in Game 2 and that’s when we’ll really find out if one team had the advantage.
“That will happen,” Rivers said. “It may happen tonight. I think one or two games you’ll get the best shot from each team and somebody will win that game.”
SHAQ UPDATE: Rivers said that Shaquille O’Neal looked good in practice on Monday in stretches but struggled at the end. the coach termed him doubtful for Game 2, but it will be a game-time decision.
“I doubt it,” Rivers said. “He looked great yesterday. He went through the whole practice. He was phenomenal actually. He had one stretch that was phenomenal. Then by the end of the practice he was struggling walking. We’ll see but I would say Game 3 is becoming likely. Game 2, were not sure but I doubt it.”
Rivers said that it was O’Neal’s first scrimmage since his seven-minute comeback against Detroit on April 3. That was encouraging, but, “Watching him walk on the bus and even this morning said the recovery time is tough for him,” Rivers said.
