The Dallas Mavericks and Jameel Warney have agreed to a partially guaranteed deal that brings the team’s roster to 18, according to the Associated Press’ Michael Scotto.

Warney is a 22-year-old big man who spent four seasons at Stony Brook University before joining the Mavericks’ summer league team and impressing in Las Vegas. The 6’8 big man backed up second round pick A.J. Hammons, generally outplaying him throughout the team’s six games while averaging about six points and seven rebounds. However, there are obvious concerns about Warney, who is small for his position (he has a power forward body and a center skillset). There was a reason he went undrafted, after all.

After his good summer league showing, though, the Mavericks had no problem bringing in Warney on a multi-year partially guaranteed deal as a training camp participant. It’s unlikely that Warney has any chance to make the team, but it’ll be good for him to make an impression on an NBA team that hopefully leads to another chance down the road.

Warney joins Jonathan Gibson, Dorian Finney-Smith and Kyle Collinsworth as summer league players who have now gotten full contracts from Dallas. They’ll be competing with players like Nicolas Brussino and Quincy Acy for the final few roster spots.
