Mike Miller is feeling better than he has since signing with the Heat, but it is not translating into playing time.

Once the Heat's entrenched sixth man and the team's best outside scoring threat, Miller is now 10th in playing time and averaging less than 14 minutes per game. He is shooting 41.7 percent (10 of 24) from three-point range, which is good for fifth on the team among players with at least 20 attempts.

Stunningly, the Heat is shooting 43 percent from three-point range as a team.

"He'll have to constantly manage the big-picture thought with his role," Heat coach Erik Spoelstra said.

Spoelstra said he is being cautious with Miller, considering his history of injuries. Miller's body broke down last season, and he hobbled through the playoffs with a sore back.
