One scout called him among the worst amateur players he's ever seen from a makeup standpoint, with top-of-the-scale arrogance, a disturbingly large sense of entitlement, and on-field behavior that includes taunting opponents. "He's just a bad, bad guy," said one front-office official. "He's basically the anti-Joe Mauer."
Buster Olney was recently talking about character issues with baseball players. He said scouts are really starting to factor in character issues and that Harper is getting the most scrutiny about this. That some scouts have even told him they hope the Nats take him so they don't have to deal with it. One of the reasons the Braves loved Heyward is his makeup and that they knew he'd be able to handle the pressure of being a superstar.
