"I already know what we have here," James said. "Like I said, I don't really read into it of what people want more of me or whatever the case may be. I will continue to find my shooters, if they're open, and I will continue to try to put pressure on the defense. If I draw two, I'll find my shooters. I have confidence they're going to knock them down. They did that tonight."
Eventually, so did James.
But it was Chalmers, who came into game with the goal of being a stopper and ended up being the guy who jump-started James.
"My main focus is to stop Tony Parker. That's my job. That's the key to the game, is not let him get going," Chalmers said. "And if the offense keeps going for me, I'm going to take it as it comes."
Chalmers finished with 19 points, and James had 17 points, eight rebounds, seven assists and three blocks — the best on Tiago Splitter's dunk attempt — while shooting only 7 of 17 from the field.
"Honestly, for me, when I was struggling offensively, my teammates continued to keep it in range," James said. " And we even had a lead at one point, especially late in the second quarter when we made that run and I was struggling a little bit.
"So I think Rio more than anybody kept us aggressive, him getting into the paint, him getting those and-ones and making a couple of 3s. It allowed me to sit back and wait for my time."
The Heat made 10 of 19 3-pointers and got 13 points from Ray Allen, and 12 points and 10 rebounds from the previously slumping Chris Bosh.
Danny Green made all six shots, including five 3-pointers, and scored 17 points for the Spurs. They host Game 3 on Tuesday night.
