To add on to that, I have a feeling this isn't Phil hiring one of his friends with a lot of championship knowledge and experience just because he's one of his friends. Phil has a plan, whether you agree with the triangle offense or bust thing or not, and he did it in a good time period (the NBA season is still going on).
I like the D-Fish also is in game shape, just coming off a Western Conference Finals series. The man still looks like a beast. Would be interesting if he became a player-coach. Either way, he could be playing with the team a lot in practice. What separates him from most (or all, I have to see the list of coaches) is that he could still play in the NBA at a good level.
I'm glad Phil took his time. He got what he wanted, and it's not like he got the 3rd, 4th, or 5th, etc. pick he had as head coach, which could be understandably worrisome. In fact, maybe Fisher was his number one choice. Maybe he offered Kerr first because Fisher's future was in question whether he'd be playing or coaching next season (or zen came into play to have one less California spot for Fisher to go to).
Welcome to the team, Fish!
