In time? He's 25. How much more time are we talking about?
Look they have similar athleticism & energy, but the comparison really stops there.
Look at physical tools. They have almost identical height, weight, and wingspan. Acy is a little bit of a better jumper but it's close. The main difference if you compare their per36 numbers is in 3pt shooting and assists. Right now Acy is a 32% career three point shooter, Draymond's career average is 34%. If he keeps working on his jumper and ball handling skills, he'd be able to do everything Draymond Green can do. Like Green, his strength and athleticism allows him to play bigger than 6-7. Court vision is not really a learnable skill, but Draymond has no doubt benefitted from being on a team with Curry and Thompson.
No one is saying Quincy Acy is going to be an All-Star or lead the league in triple doubles at any point in his career. But improving the jumper is within his control and if he does that he should be able to carve out a similar niche as a hustle points and rebounds energy guy who can defend and knock down shots.
