The NBA's already-thin free-agent pool this summer could get even more shallow with neither Kyrie Irving nor James Harden likely to move on from their current situations.

Luka Doncic, the face of the franchise for years, was traded to the Los Angeles Lakers in February in exchange for Anthony Davis. Shortly thereafter, Kyrie Irving suffered a season-ending ACL tear in his left knee during a game against the Sacramento Kings, further depleting the Mavericks' backcourt and derailing their postseason aspirations.
