I don't think he will be anything special either. Totally over hyped by the media and he has believed his own press.
His attitude of late has been awful, in matches he looks like he doesn't care all that much. He appears to have misplaced confidence imo.
His game is decent but I don't really see how it can evolve but you never know.
If he wins a Slam I will be surprised. He says clay is his favourite surface but he would get destroyed by any clay court specialist ranked 80 and above.
As you can probably tell i'm not a big fan but I don't mind being proved wrong .... sometimes
