Albies and Acuna are safest bets, IMO
Peterson will not likely be a star but I think he's going to be a solid big leaguer
Austin Riley has massive power ceiling but still some holes. Similar with Demeritte but not exactly the same story.
Apparently Cristian Pache has raised his ceiling quite a bit over the off season. Still very young, so no one can really predict, but his contact ability is pretty awesome for a young gun.
