Wow that's awful for him, he hasn't signed an extension unless they just haven't bothered to report it. I have a feeling there will be waves of players in the next year or two (Kuminga may also be in this boat?) that passed up on a lucrative extension when they were first eligible/offered that wind up getting frozen out under this CBA. There's absolutely no reason for SA to commit long term until he is unrestricted next season at this point.
Hopefully Keegan gets locked down soon.
