Why the San Antonio Spurs will re-sign Dieng
Given that Dieng chose the Spurs after being waived by Memphis despite other teams showing interest, he'd likely be the Spurs' first choice to help fill out the center rotation. Additionally, Dieng could opt to wait and see how the off-season plays out before making his decision, thus giving the Spurs a chance to re-sign him. Regarding a new contract, at age 31, Dieng may want a multi-year contract though I believe that he'd be willing to take a one-year deal for a bigger payday.
The Spurs could offer him more money than several teams who need help at the backup center position but are financially limited. Were he to re-sign, I would expect his new contract to be around a 1-year, $ 4 million deal or perhaps a 2-year, $8 million deal. While perhaps less than what some Spurs fans might expect, it's also less than half of what starting center Jakob Poeltl makes annually. Therefore, it should be enough to retain him.
Retaining Dieng would ensure that the Spurs have a reliable center rotation that is both deep and fairly versatile. Poeltl is definitely the best defensive player of the three while Eubanks is arguably the best finisher when factoring in his athleticism. Meanwhile, Dieng provides defense and outside shooting.
Despite only connecting on 31.8% of his threes as a Spur, he’s managed to expand his range over the course of his career. In the past two seasons, Dieng hit an impressive 39.2% of his 2.1 three-point attempts per game. Were he to return next season, his 3-point shooting could be better utilized in the second unit, even allowing the Spurs to play five shooters at the same time.
San Antonio could even try playing Eubanks and Dieng together against certain matchups, with Dieng playing power forward on offense. Ultimately, I feel that the Spurs will re-sign Dieng, even on a one-year deal.
