Bad game. The Warriors are really good.
However
Aldridge did not play like an all star. You're a big man. Go move Draymond Green and get buckets. You're paid a lot of money to do that. And on defense, at some point before the game is out of reach you have to at least be in the frame when someone is tossing in a layup.
Help defense was CRAP. We'd get the first rotation, but the second one was late or non-existent. Twice Leonard tried to trap off of Shaun Livingston and there was no rotation, leading to wide open dunks. Transition defense didn't get back consistently. Stupid turnovers led to those fast breaks. We got three of their starters in foul trouble, but then didn't consistently go at those players. Not a playoff effort. West was the only starter who looked like he really wanted to play. Aldridge has been playing lazy on defense for the last couple weeks.
That said, Simmons showed that he belongs on the court with anyone. He didn't score a ton, but he was aggressive (though with turnovers) and played solid on-ball defense even though he got called for some "all star missed a shot, the rookie must have fouled him" fouls. Plenty of good film for him to learn from both ways.
You live with Curry having a night like that, but you can't have 26 mostly live ball turnovers, let the defending champs turn them into fast breaks, and expect to win.
