2. Keita Bates-Diop
Keita Bates-Diop is on pace to log more than 1000 minutes this season. Be honest, did you expect that? That larger-than-expected role has been justified by his solid if unspectacular play. San Antonio's decision to re-sign him to a two-year deal over Luka Samanic looks incredibly smart given the circumstances.
Still, he isn't irreplaceable, and the Spurs could select a power forward in the lottery. That would presumably push Doug McDermott to the bench and force Bates-Diop to again earn his spot on next year's team.
3. Josh Richardson
Josh Richardson was acquired in the Derrick White trade and, despite playing well in Boston prior to the deal, he's barely played since joining the Spurs. That could simply be that coach Gregg Popovich is slowly trying to integrate him into the system. Or, it hints at the team's offseason plan to move him once again.
San Antonio could look to move him during the draft by possibly pairing him with the Lakers' 2nd round pick, currently projected to be 41st overall (thanks, L.A.). That would give playoff teams selecting in the 20s the opportunity to trade for a rotation player. However, instead of being out of a pick entirely, they'd only be trading back in the draft.
Another option would be for the Spurs to take back a player making similar money to Richardson but with another year left on his deal. That could save the receiving team money, providing additional value to justify giving up a first. That being said, San Antonio could hold onto Richardson heading into next season if there isn't a trade they like.
That would put him in a situation similar to Thaddeus Young, but Richardson has more value, so I don't expect this situation to drag out nearly as long. Overall, Richardson will probably play limited minutes the rest of the season, and it seems likely that he'll be traded, but it's unclear as to when.
