I don't think Budenholzer is a terrible choice given what a season the Bucks have had, but I also would have preferred Nick Nurse. To keep that Raptors team exactly where there were after his best player left with nothing in return is very impressive. The improvements of VanVleet, Powell, Anunoby, Davis have been great as well, so all around (winning percentage, overachiever, recognizable system, development of players) Nick Nurse met all the conditions to become COTY.
