I think the biggest reason they are hesitant on phil is they dont want a one and done situation. They need a coach thats gonna be there for a while. Phil has always been a wild card when it comes to what he is going to do.
I don't think he's that big of a wild card. He's coached the Lakers ten of the last 13 years, and it would've been more if the FO hadn't gotten burned out on him.
