No doubt he's a really good prospect. But he's still raw. Not good defensively. He struggled as a big leaguer late last year, and bombed in winter league, taking an early exit. Great tools and upside, but there's some work left to do, I think, on some fundamentals (swing, defense). Too unfinished to be placed in the very top tier, IMO.Dom Brown in AA-AAA as a 22 year old (college senior age): .327/.391/.589 with 20 bombs in nearly 400 PAs.
