The funny thing is is just the endless series of errors. You see one of those errors and you say, ok, just a mess up. I mean it's not like his skills are completely awful. I mean he looks like he knows how to play the game... but it's just one error after another. Horrible shot, pass to the other team, dribble off your foot, dribble off your hand, dribble off the other team... Hard to "diagnose" after a while other than to just say: the guy isn't very good right now.
