I don't think they'll steamroll the league. While there's only a few teams that can hang with them, most of them are out West. Look at their record when playing other teams even close to their league:
They're 1-1 against Cleveland
They're 0-1 against San Antonio
They're 0-1 against Houston
They're 1-0 against LAC
Chances are they're going to have to face 3 of those 4 teams, and they haven't steamrolled them so far. Though maybe I'll change my opinion once they get a few more games under their belt with the other tough teams in the West.
And believe it or not, short of the Grizzlies falling to #8, I think the Kings or Pelicans playing well and moving into the #8 could keep the Warriors honest. Not that either would stand a chance to take the series, but rather, having a dominant low post force like Cousins or Davis to deal with would make the Warriors at least have to keep their starters on the floor for 35+mpg, and maybe play at least 5 games. Davis for instance is averaging 35/13 against the Warriors in 3 close-ish games (Cousins has only had 1 poor game against them so far).
It could very well line up that they have to face LAC, SAS, and CLE back-to-back-to-back, which is a pretty tough road. No doubt GS is the favorites, but all 3 of those teams could give them a series, and I wouldn't be surprised for any one of them to pull off an upset.
GS is the favorite, but I'm not ready to hand them the title.
