4.) Doug McDermott
Sharpshooter Doug McDermott is entering the third and final year of his contract with the Spurs, but he may not finish out his deal in San Antonio. With $13.7 million owed to him, McDermott has the second-highest salary on the team, and large expiring contracts are usually easier to move.
That may end up being true, but with the Spurs trying to trim their roster, they can't afford to take back more than one player unless they are able to waive both of them. Or San Antonio could always be a third team in another deal, for example, a possible Damian Lillard trade. That might require them to take back a player on a contract that extends beyond next season, but they could offload two players in the process.
Tyler Herro has been rumored as an option, which would require the Spurs to move on from McDermott and another player on this list to make that work. Or perhaps they could use McDermott to take back Portland Trail Blazers center Jusuf Nurkic, who would likely be included in a Lillard trade. Fortunately, for the Spurs, they have a few options when it comes to McDermott. But it seems that each option would result in him not being on the team to end next season, possibly not even to start it.
