MIAMI — As the Heat continue to search for consistency in their fight to stay above the .500 line, Dec. 15 is just days away.

In fact, Friday is Dec. 15. Why is this worth noting?

NBA rules say free agents who signed in the offseason are not eligible to be traded until Dec. 15 or three months after their signing, whichever is later. This means the Heat’s free-agent acquisitions from this past summer — James Johnson, Dion Waiters, Kelly Olynyk, Udonis Haslem and Jordan Mickey — become trade-eligible on Friday.

There is an asterisk next to Haslem’s name, though, as he must approve any trade he’s a part of.

But don’t expect the Heat to use Friday as the green light to make an immediate trade. Miami isn’t known for making trades months before the deadline, which is set for Feb. 8 this season.

The Heat have actually never made a trade in December. The trade that brought Goran Dragic to the Heat was made in February 2015 on the day of the NBA’s trade deadline.

Despite all of that, Friday is important for one reason. It opens up more trade possibilities throughout the NBA.
