INDIANAPOLIS –— His body ached.With every move at his locker Thursday night, Mike Miller's face grimaced. He could barely bend his knees. His left shoulder was in pain. At one point Miller said the only body part that didn't hurt was his pinky. Nobody could tell, however, if he was kidding."It's that time of the year," Miller said.Through all the pain, all the aches, all the wincing, Miller found his rhythm. He got his groove back.Through the first five games of the Eastern Conference semifinals, Miller was 2-for-7 from 3-point range. He was brought on board this Heat team to stretch the floor so LeBron James and Dwyane Wade could operate with fewer bodies in their way. Against the Indiana Pacers he kept drawing defenders away from James and Wade, but when Miller had a shot, however, he wasn't converting.Until Thursday.With a seventh game on the line, Miller simply did his job. He had four 3-pointers, finished with 12 points and the Heat advanced to the Eastern Conference Finals with a 105-93 win at Bankers Life Fieldhouse."I don't think I was feeling it that much," Miller said. "I made four but I missed a couple, to be honest with you, that I would have liked to make."I was able to make a few tonight and spread the floor for those guys."But don't call Miller's series until Game 5 a slump. The 6-foot-8 forward wouldn't hear of it.He was just a shooter who wasn't knocking down his shots. Miller didn't press. He let the game to come him, like he's done during his 11-year career.Miller's 3-pointer with 26.6 seconds left in the first quarter pulled the Heat within 28-21 and sparked a 10-0 run, which he capped with another 3-pointer less than 75 seconds into the second quarter.His third 3-pointer at the 6:58 mark of the second stretched the Heat's lead to 41-35 and his final basket with 32.4 seconds left in the third put Miami ahead 76-69."When you're with a team like this, your shots come in bunches," Heat wingman James Jones said. "Sometimes they come sporadically and people get caught up in the numbers."You start to pick your spots and find your rhythm and our guys did a good job of getting him his looks. He was able to read the defense and step into some shots that were huge for us."He saw fewer opportunities this series than he did against New York in the first round of the playoffs, when he went 11-for-28 from 3.But Miller didn't hang his head. "Mike's demeanor doesn't change," Jones said. "He's such a great shooter, if he misses a shot, he's upset. If he makes a shot, he expects to make it."He's so even keel, and I think that's why he's able to weather those storms regardless whether he's shooting good or bad and come back on a night like [Thursday night] and make huge timely shots."Shane Battier wouldn't have expected it any other way from Miller.Even Heat coach Eric Spoelstra was relieved to see Miller find his rhythm so late in the series. Although, Spoelstra joked that would've like to have seen Miller defended a little more.Miller found a place every shooter does. He was cold and the only way to get out of it was by shooting his way. It was just a matter of time for Miller, as Battier observed."Any time he shoots the ball, he's got such a pure jump shot you think it's going down," Battier said. "I can't tell when he's hot and when's not. It looks so pure."
