meh, I think hell be good mentally. a fighter.
I hope so, too.
Though I've always seen him as the type of player that would go through painful ups and downs in his career, learning how to fight from the sheer drop of chances available. I'd like to see him mature as a player in easier ways, but he seems like the stubborn type and those usually need to go through something tough in their lives/careers before they learn not to take their chances for granted.
He's grown but still has the remnants of that bratty attitude that keeps good players in the juniors mentality, hopefully he fixes that sooner rather than later. /essay
That being said, hope he kicks ass in the US hard court swing this year.
