Tom D'Angelo of the Palm Beach Post reports that the Miami Heat will make a push for Tim Duncan next summer. The Spurs? Duncan is expected to opt out of his contract, one that would pay him nearly $13.3 million next season. Duncan would join the Nets' Jason Kidd at the top of a strong free agent crop.

Whether Duncan re-signs, which the Spurs expect, or leaves San Antonio, he will command a long-term deal starting at $12.5 to $13 million. The Heat are committed to about $30 million in salaries next season, and the salary cap is expected to be close to $42 million.

Duncan has dropped hints that he will return to San Antonio. He has a great relationship with the organization, and its low-key, relaxed environment fits his personality. Additionally, the Spurs have the potential to surround Duncan with a dramatically improved team. With David Robinson retiring, the team is committed to just $14 million in salaries next season, meaning it can keep Duncan, add an additional high-priced free agent, and others.

The only teams projected to have max-contract space are the Clippers, Pacers, Spurs, Jazz, Nuggets and Heat.
