I mean, I probably wouldn't have loved signing him to that last extension f I was a 76ers fan. I understand why the 76ers did it. Maybe warts would have been a better term than red flags, but the point is the same. The 76ers have employed Embiid for years now and were hoping to get the best version of him which - despite his MVPs - did not lead to much playoff success. He whines. He grifts. He's had problems with staff and teammates. He can't stay on the court. He puts up monster numbers in the regular season chasing personal accolades.
ETA: this is getting away from my original point, which is that some Max players (Curry, Tatum, LeBron) were easy, no questions asked max contracts. But other guys that get the max (Kyrie, Leonard, Embiid) have warts (galaxy brain, injuries, injuries and no leadership) have warts that you hope the good outweighs the bad.
