I definitely feel like he is the real deal, however his impact really depends on when he gets called up. I actually just traded him (I'm in a keeper league), along with Elvis Andrus, and Ike Davis for Madison Bumgarner, Jose Reyes, and Dan Haren. There is "fantasy money" involved too which I won't get into specifics, but it works out well for both teams. I just hope that if Harper is going to explode, it's not this season so I don't regret anything lol. He has a lot of pressure on him to live up to this hype since he's been 13.
