What I'd expect that he probably didn't feel like he had to say is that Jackson was ticketed for a THIRD trip through A-ball had he not been traded, and for a guy drafted ahead of Conforto, Trea Turner, Casey Gillaspie, and Bradley Zimmer, he certainly hasn't come close to keeping up with his draft class.
Again, that's not to say he isn't a wildcard with a chance to figure some things out and that it was a bad trade - just pointing out that this has a LONG way to go to becoming a steal, because to this point Jackson's done nothing to indicate he's ever going to get to The Show, much less hit 20+ bombs every year.
Garrett Spain made a great point about "prospect fatigue" in his article about Demeritte vs, Albies that seems pretty appropriate here as well. While Povse wasn't as advanced as Albies is, he's been quite good - everyone's just been hearing about him for a good while so people are more intrigued with shinier new toys (Jackson).
