Without Bogut: 9-6
With Bogut: 68-11 (Counting Playoffs)
And if you look at their defensive numbers, GS allows almost 10 points more/game when Bogut doesn't play. He doesn't put up gaudy numbers, but he completely changes the way teams play whenever he's on the court. And the numbers basically hold up his entire tenure at GS. He's not the #1 reason they are so good, but he's a very key piece of that team, and after Curry, I think him and Draymond Green are the two most important players on that team, including Thompson, Barnes, and Iguadala.
