The San Antonio Express-News reported last week that Green would likely pick up his option.
Green, 31, appeared in 70 games last season and averaged 8.6 PPG and 3.6 RPG with a shooting line of .387/.363/.769.
Although Green profiles as a three-and-D wing, his ability to knock down outside shots has wavered a little in recent years. He has converted just 35.7% of his three-point attempts over the last three seasons.
Considering that drop in performances plus his age, Green would have struggled to find a suitor who would have paid him more than his current salary. League sources told Young that Green would probably have received offers in the mid-level range ($5-8MM) if he opts out.
With Green staying, the Spurs will now have approximately $88.4MM in guaranteed salaries for next season. That figure doesn’t include cap charges for free agents Tony Parker and Kyle Anderson, or for Rudy Gay and Joffrey Lauvergne, who also hold player options — Gay is expected to opt out.
