5:00 PM CT on October 21 was the deadline for 2016 rookies to sign their contract extensions, and the Spurs achieved their goal of signing Dejounte Murray to an extension before the deadline hit, while letting it pass on Jakob Poeltl presumably to let the market determine his value when he becomes a restricted free agent next summer.
However, that doesn’t mean they aren’t anymore extension talks to be had. DeMar DeRozan, who has a player option worth $27 million for the 2020-21 season, is eligible for a extension himself.
