The DUBs gave the Spurs a beating. That is a 30 point game showing to everyone that the Cavs and Spurs can't stand a chance against them. The only reason why they could lose is if they become too complacent but if they're locked in especially if their against strong teams, it's very hard to beat them.
Usually the full potential of a team comes out during playoffs. Plus Duncan is out so probably that winning margin should be less that 10. Don't get me wrong, I give credit to Curry and the gang. 37pts in 28 mins is insane. Lets see how they play on SAS homecourt.
PS: I'm not a SAS fanboy.
