I am sorry to see Horny leave us and having Karl back in a limited role is good news. However, I hope he never becomes a full time coach. No way would Horny have brought him in. Karl gets emotional and flies of the handle whenever anyone hurts his feelings. And there is no evidence he can coach. There is years of proof that great players are often not good coaches. Even though I think Horny is going to be a good head coach, I saw no evidence that Horny made us a better shooting team - why is everyone convinced Karl will make Favors and Kanter better bigs? It could happen but not nearly as automatic as folks seem to think.
I guess you missed the quote from Horny talking about bringing Malone to Phoenix. The problem with Malone is he doesn't want to coach full-time. It isn't that he can coach. I recall Phil Jackson talking about how he thought Malone could be a coach. You are right about whether Malone can actually make a difference but it is too early to discount that he can't help/mentor our two young bigs. Look what KiKi V. did for Kanter over the summer.
