Don't Develop: Charles Bassey
Spurs backup center Charles Bassey started last season in Philadelphia before joining the team on a two-way deal. Once given the chance, he showed enough last season to warrant the Spurs signing him to a 3-year deal. But, like with Wesley, the team has an accelerated timeline, and giving Bassey more than another season to develop into a reliable backup is something they can't do.
Wembanyama, Zach Collins, and Sochan are expected to eat up most minutes at power forward and center next season. As a result, Bassey probably won't see much playing time barring injuries or rest, and even then, Sandro Mamukelashvili could compete for the remaining playing time.
To his credit, he is more ready to contribute than Wesley, and he is a cheap and athletic center, so there is a path for him to earn limited playing time as the fourth big man. On the other hand, if he doesn't, then the Spurs could have him compete for a roster spot after next season in training camp and in the preseason. The Spurs don't need to give up on him just yet, but with a crowded frontcourt and limited roster space, that may soon be the most likely outcome for Bassey.
