I think the key player is Kingery, he just looks totally different than last year (or what prospects are supposed to do, deal with adversity and take a step up), really good bat speed, as he learns to recognize offspeed pitches he could get even better - looked a bit shaky in CF at first, but has the speed to outrun his mistakes as he learns.
In two years they could have Hoskins, Kingery, Grullon, Bohm, Moniak and Haseley on this team.
