I'm less concerned about the "need a creator" situation for 2016. Look at 2013. The only creator on the floor was Burke (granted, he was National Player of the Year). You can't credibly argue Nik was a creator during our NCAA run, as he was awful in most of those games (Syracuse and Louisville in particular).
Irvin is now capable of creating mid-range shots for himself, and using the pick-and-roll to find a big man rolling to the basket. Walton, prior to his injury, can get into the lane and either score for himself, or pass to others. MAAR can get a shot for himself off the dribble pretty consistently, though I'd agree he's not great at using the dribble to find others. And I think in two years, Chapman will be a capable dribbler and passer (he's already shown glimpses of being a good passer).
Last year was really the first time we've had multiple wings, in addition to the point guard, who could handle the ball effectively. Heck, look back to the VCU game, where we let Tim bring the ball up the court against the press and I'm sure every Michigan fan was collectively holding his breath early in that game to see if he could do it capably (turns out, not too bad). Sure, it would be nice to have a team full of guys who are creators, but I don't see it as essential.
Let's put it this way - the 2012 team won a share of the Big Ten title (with two really good teams, MSU and OSU, both of whom we beat at home that year), and among Morris, Hardaway, Douglas, Novak, and Smote (the PG and top wing players), I'd give the edge to the 2016 squad in terms of guys who could create offense off the dribble. As a freshman, MAAR is already WAY more capable of scoring off the dribble than Douglas ever was.
