That isn't horrible value for the Heat. Stretch big who can defend adequately. A bit soft as a rebounder, but otherwise pretty well rounded player.
I'd take Olynyk's contract of 50 Million over 4 years over Mozgov's contract of 64 Million over 4 years. Not a bad signing for a 7 foot center who can shoot 3's, handle the ball and shoot over 70% for FT's. He'd be a pretty good PF in Miami and stretches the floor a bit for the Heat. Definitely worse contracts out there for unproven players. Otto Porter for max
