He won't get burnt out. This is all he wants. He's no more likely than anyone else out there, ya know?
My only concern--is I want him in Washington AT LEAST until he's 31 or 32. period. If that means 10 years at $300 million when he's 21 (I believe he'll be one of the top players in baseball as soon as two years from right now) then so be it.
I am selfish, I do want him beyond his arbitration years, and so what if I do. The guy has rejuvenated my love for this game. I am selfish when it comes to Harper and to a lesser degree, Stras. But Harper is the future and the present and all that. He is the crown jewel of our baseball camelot. You do whatever it takes to keep him, period.
