I would say that sunsfan88's question is not about what Hornacek coaches, but rather the roster that the Front Office has provided.
Two lead Point Guards last season. Three lead Point Guards this season. If I were the Coach, I'd be pissed and feel trapped. What's next? Signing the Gorilla to a contract and putting a trampoline on the court?
Say this 3 times. "The Suns best three players are PGs. The Suns best three players are PGs. The Suns best three players are PGs."
What owner would allow his Front Office to stock a 5-player professional sports team that way? A banker, that's who? There's a lot of population in the Valley. Get those turn styles going. It is not about the art of basketball.
