The guy has the goods for sure. He's going to be fun to watch for a long time.
260/300/400 is probably a realistic projection for next year. Hopefully we don't see a lot of overreaction to the fact that he won't be Trout or Harper in his first full season. He definitely has some flaws that need to be ironed out.
Anyway, I think he's an All-Star by 2016.
