2. Keita Bates-Diop
Considering how his time with the Spurs started, what Keita Bates-Diop was able to do this season is notable. He averaged double the minutes he did last season (and doubled his scoring average), started 14 times, and dropped a 30-piece on a team everyone had penciled into the NBA Playoffs.
There were several times Bates-Diop's size was needed at the forward position to fight on the glass or guard some of the bigger wings, and he did a serviceable job doing so. I'm just not sure the Spurs absolutely see him in their long-term plans.
According to HoopsHype, Keita's money isn't guaranteed next season. The $1.87 million left on his deal will only become guaranteed if he isn't waived by the first day of the 2022-23 season. I expect San Antonio to be wheeling and dealing all throughout the offseason, and even that small amount of money plus a roster spot could be enough for them to cut him loose.
Keita gave us all this lasting memory of dropping 30 points on the Los Angeles Lakers on a perfect 11-for-11 shooting night. Considering that directly helped them miss the Play-In Tournament, that would be a pretty fun parting gift if he ends up moving on.
