4. Isaiah Roby
Isaiah Roby has been one of the biggest disappointments for San Antonio this season. His statistics and efficiency have taken a nosedive across the board, and he only broke into the rotation when a packed injury report left Gregg Popovich with no alternatives. The waiver-wire addition has looked more than a little tentative and uncomfortable from day one.
With Keita Bates-Diop and Doug McDermott cemented above Roby on the team totem pole and youngsters like Jeremy Sochan and Dominick Barlow taking precedence during the rebuild, there might not be room for the 25-year-old forward in Alamo City. Suffering a sprained ankle right before the All-Star Break has done nothing to help his cause.
5. Julian Champagnie
The last name on this list might be surprising since San Antonio inked him to a two-way contract less than two weeks ago, but Julian Champagnie is far from a lock to return next season. His recent deal is merely an audition with the G League affiliate, and it will be much shorter than the ones guys like Drew Eubanks and Quinndary Weatherspoon enjoyed.
Champagnie has posted 15.7 points and 5.7 rebounds in three games with the Austin Spurs, but it has come on ice-cold 29.2% shooting. Though you can never read too much into a small sample size, the G League season is coming to a close in March, and that means there are just ten more games for the rookie to prove to PATFO that he deserves an NBA promotion.
