Yeah, would be hard to justify ever giving him minutes over Wade, who's already on the team and arguably has more potential to develop into a handy roleplayer.
Best case for Wade is lesser Ryan Anderson. Maten is a better athlete and has some defensive upside. Neither will ever be a guy who gets over 20 MPG. But both have the potential to provide something but are both likely Gleague fodder who gets a taste of the NBA before sliding into post basketball careers or Europe.
