I don't think it will be a failure to improve so much as a failure to become consistent. He is completely overwhelmed by his emotions when he plays. Which is great . . . when he's hot. But when he's not, he enters some sort of dark hole and it takes him forever to dig himself out.
He's also just turned 22. It would be one thing if he was entering his fourth season at 26 or so but hell, he's done more already than a lot of players will ever do. To say he is who we think he is or whatever is incredibly short sighted. Much like saying he'd be the next Mickey Mantle was.
