"It's impossible to find any talent evaluator who isn't blown away by Harper's ability on the field, but it's equally difficult to find one who doesn't genuinely dislike the kid. 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.'"
