He's pretty awesome and shows sick touch with drop shots and occasionally volleys, but this is a crucial year for him. He caught fire at one big tournament last fall and is suddenly a seeded player, meaning he is expected to win 2-3 matches per tournament. He'll have to do it easier than this for sure.
He is a nice guy, seems very humble in interviews (talks a lot about how it was a financial burden playing until 2012), but I get the sense he is still very raw and the grind of the tour might be emotionally difficult to handle at first. Might not be ready to contend for the biggest prizes for another 2-3 years. If he makes it at this level until then, he is a keeper.
