9/year would be a great deal, tbh..it's bench player money, at this point, and it would eliminate the risk of paying Simmons solely based on 2 weeks of good playoff basketball(his only good stretch in a Spurs uniform in 2 years)..look at the $ guys like Allen Crabbe received, last off-season, for example..
If I'm Simmons, I take all the money I can get, though..he has potential, but again, he's getting paid based on 2 weeks of basketball, following consecutive Regular Seasons where he fell out of the rotation by the end of the year..if a team is going to give you huge $ based on a stretch you may never replicate again, take it and run..
