DaRon Holmes II

Ever since march and someone brought up to draft him I've been glazing him so hard. He can pass well, shoot the three at a solid clip (something I only expect to get better if he's coached by England), plays solid defense, can dribble and score on his own, and he also looks big and strong enough to really help our rebounding. He's a little older (22 in August) but that fits the age of our team well. Can someone explain why we shouldn't draft him? He looks to me like the piece we are missing and possibly the player that takes us from a great team to a championship team if it all works out
