Even the best teams in the league are looking to improve with the trade deadline less than 10 days away.

The Heat are 28-9 on the season, but are looking to make some upgrades as they head into the playoffs.

Miami is looking to improve their frontline. The Heat have reportedly contacted teams looking for a backup big man.

After it looked like Rasheed Wallace might come out of retirement to sign with the Lakers, the forward may sign with the Heat.

Miami has reportedly worked out Wallace in an attempt to find a quality big man to back up Chris Bosh and Joel Anthony.

Wallace last played in the 2009-2010 NBA Season. That year, he averaged nine points per game and 4.1 rebounds per contest.

The Heat were in the market for Joel Przybilla and Kenyon Martin a few weeks ago, but both players signed with other clubs.

Chris Kaman has been on the trade market since being moved to New Orleans in the deal that landed the Clippers Chris Paul. Golden State, Boston and Miami have all been rumored to have interest in the center.

The reports come less than two days after the Heat had trouble with the Lakers frontline in a loss to Los Angeles. Andrew Bynum and Paul Gasol combined for 23 rebounds.

Joel Anthony is averaging 3.2 points, 4.3 rebounds and 1.2 blocks per game as Miami's starting center this season.
