It's like his prospect value has barely moved since the draft. Obviously he can hit, the stats/peripherals/age are good (he was the 6th youngest qualified player in the California league), but he needs 60 game power if he's ever going to be a useful MLB player.
If he was a Mets prospect everyone would love him. It basically all comes down to whether or not he learns to hit with power consistently in games. He's not going to be a guy like Smoak who will hang around until he's 30 getting a chance to figure it out because of defense, a good work ethic, etc.
I wouldn't care about owning him in, say, a 20 team dynasty league. Meh. Fat.
