Mike Brown....Maurice Cheeks....Larry Drew....Mike Woodson.....etc.
At what point do GM's/Owners realize these guys can't win? All of these guys will probably be fired from their respective teams within the next year, but I can almost guarantee all will re-surface as a HC at some point.
I think one answer is that there is a short supply of quality NBA coaches. But I'd rather hire an assistant who has paid his dues than hire a guy who has failed multiple times before. Kudos to PHX and ATL for hiring Hornacek and Budenholzer. Good hires.
