Is this a good build?

NBA 2K17 So I spent forever and ever saving up like 150k vc and I created a 6'6 sg 220 pound shot creator. People tell me he is way to big and will be extremely slow. Did I waste my money and time? I wanna take him to park. everyone is like 6'4 at max with like 190 pounds... EDIT: He also has max wingspan and shoulder width.
