League and team sources confirmed Wednesday that Miami is in its ``due diligence'' process in regards to exploring a trade for Amar'e Stoudemire.

If Miami is reluctant to package Michael Beasley in a potential offer for Stoudemire, then Jermaine O'Neal and a first-round pick might entice Phoenix.

But the Heat have also not ruled out trying to re-sign O'Neal this summer.
