Spurs quietly just solved a frustrating flaw that's plagued them

Just weeks before the start of training camp, the San Antonio Spurs are still making moves. We love to see it. This time, ESPN's Shams Charania announced that the Spurs had re-signed big man Bismack Biyombo, filling their last roster spot.

Bringing Biyombo back might seem like a questionable move considering that the Spurs are well-stocked at center, but there's logic to bringing him back. The Spurs' weakest position by far last season was at center, and they have made a concerted effort to address that weakness.

Biyombo played surprisingly well after being signed to help fill minutes after Wembanyama was ruled out for the season. He sets solid screens, rolls to the basket, and has decent hands, allowing him to finish at the rim.

Biyombo is also a tremendous rebounder and a more than capable shot blocker. That left a strong enough impression for GM Brian Wright to bring him back as a deep bench guy.

Bismack Biyombo will quietly play a key role for the Spurs

He probably won't play much, but he will still have a role on the Spurs. For instance, with him they will have three centers, which is especially beneficial during training camp and practices. That would allow for at least three five-man teams, helping them scrimmage.

As far as depth, if the Spurs consider Kelly Olynyk to be more of a four than Harrison Barnes, then Barnes, Jeremy Sochan, and Olynyk would be the power forward rotation. Meanwhile, Wembanyama, Luke Kornet, and Biyombo would be the center rotation. If Biyombo is the third center, then re-signing him seems more than reasonable.

Wembanyama will hopefully be healthy this season, playing at least 70 games after having last season cut short due to deep vein thrombosis. In that case, Biyombo likely won't play a major role, but he gives San Antonio insurance in case Wembanyama misses time.

Were that to happen, Kornet would step into a starting role, while Biyombo or perhaps Olynyk would fill in behind him at backup center. The Spurs could do a lot worse with a third center, with Biyombo effective at the basics, making him tailor-made to contribute in limited spurts.

All told, the Spurs re-signing Biyombo should prove to be a smart move that gives them much more depth at a position of weakness. While he likely won't play consistently, simply having him in case he is needed gives San Antonio an insurance policy if Wembanyama is out for an extended period of time.
