I don't understand your point. The whole team can shoot now. That's the idea. Yes, he will shoot. So will Hawkins, Newton, Johnson, Karaban and even Jackson. Nobody is replacing Polley because it's a role that you don't want replaced. He never fit.
He's a much different and much better player than Polley. Polley couldn't handle like a guard, pass like a guard, attack the basket like a guard, or shoot on motion at all. He was tall, but slow as hell and so couldn't guard guys smaller than him. He was also weak and not a good jumper so couldn't guard guys his size. Note that they are about the same weight. Note that the 6'4" guy outrebounded Polley substantially. Look at Polley's assist numbers, worst on the team among guys who played 100 minutes.
