Former Golden State Warriors power forward David West thinks the Houston Rockets, and not the Oklahoma City Thunder, are the biggest challenge to the Dubs this season.

The Warriors and Rockets met in the Western Conference Finals last season. Golden State won in seven games.

Many believe if Rockets All-Star point guard Chris Paul didn't hurt his hamstring in Game 5, it would have been Houston advancing to the NBA Finals and not Golden State.

The Thunder are playing really well this season. Small forward Paul George is playing like an MVP and point guard Russell Westbrook is a walking triple-double.

However, because the Rockets have James Harden, David West believes Houston is a bigger threat to Golden State once the postseason starts:

“I love OKC, and I love PG (Paul George) obviously,” West said on FS1's First Things First. “But I think the Rockets. Harden is probably the best one-on-one guy we’ve seen, ever, in my opinion. The way he can control the game with his dribble, even with everyone looking at him…if he’s healthy, I think they’re gonna be the toughest challenge because nobody has proven they can guard that dude.”

Harden leads the NBA in scoring at 36.1 points per game. Houston went 3-1 against the Warriors this season.
