So the full number is $21 million with the incentives, not plus incentives. Also I see nothing there that indicates that he gets the other $5 million just for being on the team.
21 if he plays both seasons. Between 21 and 16 (Prorated) if he plays less than 2 seasons and is released. 22 million if he plays both seasons and meets his incentive thresholds. If they release him tomorrow he still gets $16 million.
