Mike Miller might sometimes feel like a forgotten man on the Heat’s bench, but his folk-hero status among fans, earned in 2012 NBA Finals, has only grown with passage of time. Hobbled by a balky back, Miller hit seven three-pointers in Game 5 against the Oklahoma City Thunder and, in doing so, shot his way into the long-term memories of not only Heat supporters but basketball lovers everywhere. It’s nearly that time again — time for another run at a championship — and Miller reminded all of his shooting prowess on Tuesday in the Heat’s 12-point loss to the Knicks at AmericanAirlines Arena. His name might not have the same cachet as Ray Allen, but his game, now emboldened by a healthy body, wants for nothing. “You’re happy for him that, one, he’s healthy this time of year and, secondly, he has a unique skill set because he can not only shoot the basketball from three but he can put the ball on the floor and he’s a very good rebounder, and I think you saw the whole package [Tuesday night],” Heat coach Erik Spoelstra said. Miller finished the game with 18 points, all coming in the first half, and was 7 of 12 from the field, including 4 of 8 from three-point range. It was the most field goals he had made in a game this season. In addition to the shooting, Miller was tied with Shane Battier for a team-high eight rebounds. Yes, the Heat lost Tuesday, which is rare these days, but the game certainly felt like a win for Miller, who was mobbed by fans as he was trying to duck out of the arena without answering questions from reporters. Such is Miller’s custom whether he hits four three-pointers — as he has done in back-to-back games — or doesn’t register a single field goal, which has been the case in 19 of the Heat’s games this season. Always gracious, Miller and his quick exit were slowed by adulation and then stopped all together when a reporter tracked him down just as he was nearly home free and about to reach the parking lot underneath AmericanAirlines Arena. The obvious question: Do you feel like these next few weeks are a tryout for playing time in the playoffs? “I’m in a tryout for sure,” Miller said. “It’s going to be tough to get in there. I’m not naïve to it. We’ve got a pretty good rotation going on and we won 27 straight games with that rotation. “But if they call on me, I’ll be ready to play.”
