I think he can toggle between 4 and 5 fairly reliably... if Quin adjusts some schemes/principles. At very least he can get some steals while playing drop coverage and we will kill it on offense while maybe surviving on defense. He would help us size up when we need to.
Injuries are an issue... he's also never really been on a winning team for a long period of time... he had the finals run with Lebron. He's a guy I could see being awesome or just being a slight disappointment. I think he's a good guy to bet on.
