The shine has worn off on him and he may never amount to anything, but the trade makes a ton of sense. Lot of power and just hope he figures how swing mechanically (too long). I would move him back to catcher where he's not asked to hit as much, but talk is that he's too big and stiff now to play catcher.
High upside/low chance of getting there is fine for 2 fringe pitchers in a crowded 40 man roster.
