The second-year man out of Kentucky has played just 10 minutes over three games this season:
"Everybody wants to play," Harrellson said, "but I'm playing behind a bunch of All-Stars, a bunch of guys that have been in the league, world champions. So I can't really complain about who's playing in front of me at the moment. I'm just staying ready, keep working."
So far, that's meant wearing a sports coat more often than being in uniform. This from a player who dressed for every game last season as a rookie with the New York Knicks other than the 19 games he missed after fracturing his right wrist.
"It's really tough," the outside-shooting big man said of showering before games and then changing into street clothes. "I wasn't used to it. The first five, six games, it was kind of mentally draining, thinking about not dressing. But right now, my mindset is a whole different level. I'm just going out there and supporting my team.
With the Knicks last season, Harrellson played in 37 games and started four. He averaged 4.4 points and 3.9 rebounds per game.
Harrellson was the 45th overall pick in the 2011 NBA Draft, but was traded to the Knicks for cash. In July, he was traded to the Houston Rockets, but was waived just over a month later. He signed with the Heat on Sept. 17.
Harrellson, 23, played in 38 games with the Wildcats in his final collegiate season. He averaged 7.6 points and 8.7 rebounds per game. He was on the floor for about 29 minutes per game.
Chris Bosh is the Heat's primary center now. Bosh, 28, is averaging 19.3 points and 7.9 rebounds per game. Joel Anthony has been the primary backup, playing 50 minutes over 11 games.
