The Miami Heat are the defending champions and currently have the best record in the Eastern Conference. But even the best teams have some weaknesses, and the Heat should definitely address these issues in the near future.
The Heat are 18th in the league in scoring defense, allowing opposing teams to score 97.7 points per game—a far cry from the fourth-ranked defense that they were last year.
They're also the second-worst rebounding team and worst offensive rebounding team in the league. The Heat weren't a good rebounding team last season when they won a championship either, but this season, their mediocre rebounding is a major reason why their defensive efficiency is so low.
Fortunately for the Heat, there are a few players in free agency who can help them.
Although talks of Kenyon Martin signing with the Miami Heat in early November have fallen off, the Heat should still consider trying to get this guy.
He didn't really show much of an offensive game last season with the Los Angeles Clippers, and it seems like Martin's plethora of injuries throughout his career has finally started breaking down his body as he takes a step closer to retirement.
With all that being said, there are some qualities that players don't lose when they get older. Martin's toughness and aggression down on the block is something the Heat are sorely lacking.
The Birdman has recently been working out with the Miami Heat, so that's already a good sign that the Heat are still attempting to remedy their rebounding and defense concerns.
He has produced 11.0 PPG, 10.5 RPG, and 3.2 blocks per 36 minutes over his career with a total rebounding rate of 17 percent. Like Kenyon Martin, Andersen is as tough and physical as they come, so it's unlikely that the Heat would let him slip away.
Milicic is a legit seven-footer and a big body that can crash the boards as well anyone. Per-36 minutes, Milicic yields 11.2 points, 8.2 rebounds, and 2.6 blocks per game, which are far from impressive, but decent enough for his role on the team.
Offensively, Milicic may be the biggest liability the league has ever seen, and he registers a career -3.8 offensive win shares to prove it. If the Miami Heat are unable to sign Chris Andersen, Milicic would probably be the next best free agent that they can get.
Dan Gadzuric is so unknown that the last time Bleacher Report had him in a relevant article was nearly a year ago.
All jokes aside, Gadzuric's rebounding and experience in the league would have a positive influence on the Miami Heat without question. He has a total rebounding rate of 17.4 and gets in 10.7 rebounds per-36 minutes for his career.
Unlike Darko Martin and Chris Andersen, Gadzuric has never been a pioneer of controversy. You shouldn't expect many problems off the court or in the locker room with Gadzuric on your team. He'll remain the same as he's been his whole career—a good rebounder who lives off the grid.
