There are a couple of schools of thought when talking about Ric Boucher saying Zion won’t live up to the hype and is not as NBA ready as Luka Doncic. Some of that is true and some of it isn’t and some of it is based on upside vs NBA readiness.
Certainly Doncic entering the NBA should’ve been more ready he’d played years of pro-ball throughout his life and came in as a professional already – and certainly Zion will be coming into the league the more traditional route of being a college player that has to transition into pro-ball is a completely different animal.
