I don't think the refs were the problem. GS had all their big men in foul trouble in the second half, the two stars were ordinary, and yet the Spurs just couldn't put it away.
As far as the future, fans and apparently the front office are afraid to break up the big 3. They could have traded Manu and/or Stephen Jackson this year for Al Jefferson. Manu, when he's not hitting shots, is useless. He can't defend, he turns the ball over, he takes bad shots. I've been saying this for three years. But people get blinded by the 1 in every 3 games he actually does something.
