Haas is acting like he is some robotic programized Goat, not like a guy who is enjoying in last few months of professional tennis. Opponent hits a winner and he starts to talk with everybody, hitting the balls, unsatisfied with everything like he missed the easiest balls. Then if opponent hits the line the same story etc... The best example was Dupuis match a long ago in Wimby . And he is more or less like that all the time
You sir, only pretend that you know Haas.
That talking to everybody, is actually talking to himself, just remember that priceless monologue at AO 2007.
He's only like that when missing easy shots, you will NEVER see him STARRING at opponent after winning point, or loudly and sarcastically celebrating it.
