OAKLAND (Bleacher Report) -- Coming off of an impressive overtime victory over the NBA's best team, the Golden State Warriors may have officially declared themselves dark-horse contenders.

At this point, what the Warriors have done can no longer be considered a fluke. Based on what is now a 55-game sample, it's clear that Golden State can score with anyone. Their offense has rated as the league's ninth most efficient this season, and their defense had been nearly as good until a wicked six-game skid that saw them allow 117.5 points per game.

Overall, though, the Warriors have undergone a massive transformation after rating as the NBA's worst rebounding team and fourth-worst defensive outfit a year ago.

Huge wins over good teams helps bolster Golden State's case as a sneakily dangerous club.
