When they had their starting five. The problem was that they didn't have their starting five for the playoffs. They were missing their starting and back up centers against the huge front court of the clippers. Jordan and Griffin dominating the boards was the difference in a seven game series.
Don't get me wrong, I prefer kerr to Jackson, but to act like the system has made curry is wrong IMO. He was fantastic last year without the system. And the year before dominated a first round series with the nuggets and half of a series against the spurs.
If Ginobili doesn't hit a last second shot due to a defensive breakdown, the warriors would have been up 2 games and going back home.
Curry was set up for a career year with our without a coaching change. Guys like Harrison Barnes and D. Green have benefited the most from Kerr.
