It's when you ask him to be a primary playmaker and ballhandler that you're going to run into serious roadblocks.
No-one has, or is asking him to do this. At least not in the sense I understand the role of a basketball playmaker (call plays, control the tempo, manufacture shots when plays break down).
I've seen him asked to do two things:
1. Bring the ball across half-court.
2. Participate in offense-by-committee.
The problem is that every time he has to do anything else than sit in the corner or cut to the basket for open layups, he's been exposed for his lack of reliable fundamental basketball skills.
