Mario Chalmers, G, 6-1, Kansas -- Nice player acquired in draft-night trade with Minnesota. He should contend for minutes at backup point guard. Not likely to enter the season as the starter, but a solid addition.

BIGGEST NEEDS: Miami has to get a point guard and a center. And more specifically at center, Miami needs someone who can rebound and defend the rim. Most likely the Heat has to go the free agent route at both positions. But there are trade possibilities with F Shawn Marion, who is in the final year of his $17.8 million contract. Heat president Pat Riley continues to insist Marion will be on the team for training camp, and that Miami will try to negotiate and extension.

FREE AGENT FOCUS: Miami still seeks a starting point guard and starting center. But everything could depend on what the Heat does with F Shawn Marion. He's attractive trade bait to acquire a pair of quality players. But he's also a uniquely talented player who could help Miami tremendously. The problem is there's not much of a future for Marion in Miami because of his desire for a contract extension.

"We made him what we felt was a very good offer," Heat president Pat Riley said, "and we never got an offer back."

Depth seems to be OK for now, although a seasoned veteran or two could be needed. It appears F Dorell Wright and G Chris Quinn will return to provide depth at small forward and point guard. G Marcus Banks also provides depth at point guard, as does rookie G Mario Chalmers.

Miami has to decide if it wants to offer swingman Ricky Davis a contract. He'd add excellent depth, too. G Daequan Cook offers depth at shooting guard, although Davis is the better choice the way the roster stands now.

If Miami finds a starting center it has veteran Mark Blount as a backup, which is good. And if the roster stays in its current form, either Michael Beasley or Udonis Haslem could come off the bench, providing even more depth.

And C Alonzo Mourning is still trying to rehabilitate his serious knee injury.

PLAYER NOTES:

--F Shawn Marion is an Olympic alternate who could be selected to join the team if injuries mount. Marion still doesn't have a contract extension from Miami. Heat president Pat Riley said the sides would work on an extension sometime after training camp opens.

--G Dwyane Wade is having trouble keeping his new sports-themed restaurants -- D. Wade Sports Grill -- open in the Miami area. Two of three are already closed and a third hasn't yet opened. And now, according to a report, Wade is being sued by the restaurant's partners for breach of contract, saying, among other things, Wade failed to deliver on personal appearances to promote the eatery. One location in Fort Lauderdale closed in July after being open just four months. A location in Boca Raton closed in April after being open just three months. A North Miami location has yet to open.

--C Alonzo Mourning said he might not return, if he returns at all, until mid-season. Mourning, 38, continues working out in hopes of returning from a serious knee injury sustained in January. It was originally thought Mourning might return for training camp, but he recently said the injury would require a one-year recovery period.
