Greg Oden

Pat Riley said the Heat remain interested in free-agent center Greg Oden, who is expected to defer his decision until next month as he works his way back from career-long knee issues.

“We do have interest in him and we will track him,” he said.

Riley said the Heat were not in contact with center Andrew Bynum, who ultimately took a free-agent deal from the Cleveland Cavaliers larger than the Heat could have offered.

As for spending more on coach Erik Spoelstra, whose contract is approaching its end, Riley said, “He’s one of the family here and as soon as that is broached, I’m sure it will be broached in a very positive manner.”

Under the new formula that goes into effect starting this coming season, the Heat, by currently standing $16 million over the $71,748,000 luxury-tax threshold set Tuesday by the NBA, would have to write a tax check to the league of $33.6 million at season’s end.
