Lots of players have a casual demenour when they play, but that doesnt mean they dont care about the outcome. Its ridiculous to suggest his coach should leave just after he makes the QF of Indian Wells
People used to say the same thing about Federer too, he always looked like he didnt care, but look what he has done now. Sometimes Moya looks like he doesnt care either. Stop overreacting, I'm sure Blake was trying hard.
