use glock like the bulls used paxson and kerr: nail 3s
if he can do that consistently, he'll get some playing time
kerr was something like 45% from 3 over his 15 or 16 seasons. he also hovered around 50% shooting from the field in those 5 season with the bulls and 52% from 3 for a few of those years. i dont think glock can ever do that, but i feel you on the way they can use him like that though it will either be situational or when others are cold.
hopefully he is a polar opposite from his spl
