Warriors must bring energy, focus on defense to prove naysayers wrong

Editor's note: Grant Liffmann (@grantliffmann) is the co-host of Warriors Outsiders, which airs on NBC Sports Bay Area 90 minutes before each home game and 60 minutes after every game. The Warriors' roster upheaval has been significant and dramatic. After years of historically great offensive output, the team will try to find a way to make up for nearly 55 points per game lost after the departures of Kevin Durant and Andre Iguodala, as well as Klay Thompson, who will be out until at least February as he recovers from a torn ACL.
