The Spurs are heading into free agency with their roster almost full. On Monday, they re-signed Julian Champagnie and Harrison Barnes to keep their rotation players from last season in place, and will head into Tuesday with 12 standard contracts, including the rookie deals for their two recent first-round picks.

The moves were not surprising at all. San Antonio reached the NBA Finals last season, after all, and can count on internal development from their young players. The team didn’t have cap space, so securing a deep roster before adding the final touches with some additions was always the likely outcome.

Let’s take a look at where the roster stands now and what’s likely to happen when free agency officially starts.

Before looking ahead, it’s important to note that the Spurs didn’t have to overpay their own free agents.

Champagnie had a team option on the last year of his deal, but the front office declined it and got him paid a summer sooner than he would have had they waited. They essentially gave them the equivalent of the full mid-level exception worth $15 million a year on a contract that declines in value, which is another smart detail. As a result, they locked down a 25-year-old wing who shot 38 percent from outside on high volume and is a solid defender. Just a good deal for a good player.

Barnes lost his starting spot to Champagnie last season, and even in the playoffs, he occasionally saw Carter Bryant leapfrog him in the rotation, so he could have decided to leave to try to get more playing time elsewhere. Instead, the veteran agreed to a one-year, $8 million deal to stay in San Antonio, which shows that he’s comfortable with the organization. A case could be made that he likely would have made less in the open market, but the short duration of the contract makes up for it and gives the front office a tradeable expiring piece if the two sides decide to part ways during the season.

A very quick look into the Spurs’ cap situation reveals that they have around $181 million in committed salary, counting the rookie scale contracts for their two first-round picks. The cap is expected to be set at an estimated $165 million, and the tax line at around $201 million. Again, these are estimates, but the picture is clear: San Antonio can use the entire mid-level exception worth $15 million and not venture into tax territory, mostly because they remained disciplined in the past trade deadline.

There was a good case to make back in February for the Silver and Black to use the expiring contracts of Kelly Olynyk, Jeremy Sochan, and Barnes to make an upgrade at forward. The problem is that most teams trading for expiring deals are trying to shed long-term money. Had the Spurs traded, say, Olynyk for someone making eight figures in the upcoming season, it would have been hard to retain Champagnie and Barnes while still having enough room under the tax to add someone else now. It seems like the plan was to prioritize flexibility to keep the rotation intact and potentially make an addition in the summer.

The Spurs have the full mid-level exception at their disposal and enough room to use it fully on one player while still being under the tax line to round out their roster. They have been linked to most shooters with size, a list that includes Tobias Harris, John Collins, Dean Wade, Sandro Mamukelashvili, and Rui Hachimura. Some of those players might sign for less than $15 million a year, but even in the best circumstances, they would command most of the exception. And they could definitely help a San Antonio team that was a man short in the playoffs. The problem is that while San Antonio has money to offer, it might not have playing time in the regular season.

The Spurs’ depth chart stands as follows:

PG: Stephon Castle – Dylan Harper

SG: De’Aaron Fox

SF: Devin Vassell – Carter Bryant
