Both Golden State and Chicago are 0-2. All of these losses were by blowouts, too. But there's a major difference. The Warriors were buried by the Bucks and Nets, probably the two best teams in the Eastern Conference. The Bulls lost big to the Pacers and Hawks. 
Billy Donovan certainly has his work cut out for him in his first season as Bulls coach. Chicago surrendered 124 points to the Hawks and 125 to the Pacers. Defense is a real problem for the Bulls. The loss to the Pacers came on Saturday.
The Warriors are the more rested team having last played on Friday. Center James Wiseman, the No. 2 overall pick in the draft, already is displaying his potential scoring 18 and 19 points, respectively, during his first two NBA games. Stephen Curry gives the Warriors the best player on the court by far and there's a good chance Draymond Green makes his season debut here for the Warriors. 
Big coaching edge, too, for the Warriors right now with Steve Kerr against Donovan.
