Heat forward Mike Miller admits he feels a little guilty.

He was supposed to be in the running for the Sixth Man of the Year Award. Instead, the likable shooter could be considered one of the NBA's biggest individual disappointments of the regular season. The significance of that statement is not lost on Miller, who has struggled this season due to injury.

"You do feel guilty at times because you want to be able to do more and help but I have to make sure I'm healthy for the stretch we have left," Miller said.

At this point, that's the most important thing — that Miller is as healthy as possible for the Heat's playoff run. He has played in only 36 games this season because of injuries, including torn ligaments in his thumb, a nasty series of blows to the head and, most recently, a bruised right knee.

After missing the Heat's first three games of road trip, Miller played extensively Sunday against the Nets.

The Heat signed Miller this offseason to spread the floor and provide a consistent offensive weapon from three-point range to complement Dwyane Wade, LeBron James and Chris Bosh. Instead, Miller is shooting 37.5 percent from three-point range and 40.1 percent from the field.
