I am not certain how good is Nick Nurse, however from reading about him, it appears that The Raptors is coached by a newbie in this level hehehe.
I reckon another 2 years of experience might bring him to a championship challenge.
That newbie bring the Warriors to the ECF, that does not looks newbie to me.
Game is not yet over, Bucks are really expected to win here since they are the heavy favorites.
Look at the coach of Rockets, Mike D'Antoni is no newbie but his team cannot beat the Warriors even without Durant on their last game.
