How many of us on here have the talent he does and were treated the way he's been treated. I've seen a lot of hyped high school athletes think they were better than they actually were. Some flame out, some grow up and realize their potential. If he's still acting like this after a year or three of pro-ball, I'll be more concerned, though it will probably mean he's been tremendously successful.
Obviously none of us have his talent. Also, we've probably never been babied through life like Harper has... but the kid is a dick. Plain and simple.
I hope he grows up and is great for the Nats... but in a sport filled with jerks, Harper looks like he's at the very top of the list.
