The image of Mike Miller urging Lebron to get up (from a timeout) during the last few minutes of the game says a lot. Being their leader (and the best player in the world), I thought Lebron would fight until the end. It looked like he gave up a little too early. Good thing JR Smith made it more interesting in the end.
As for the Warriors, the x-factor was a steady veteran in Iggy. He became the leader of the young Warriors team when it mattered the most. Congrats GSW! Time to celebrate!
