Klay Thompson said last week that the Golden State Warriors are "trying to win every game going into the playoffs."

Maybe that's not realistic, but the champs are one of five teams (all in the Western Conference) that haven't lost since the All-Star break and have started to play better defensively. When they're focused, the Warriors can be the best team in the league on both ends of the floor.

Of course, if the Warriors are going to try to run the table, the Houston Rockets have to stay just as locked in. The Rockets have won 15 straight games, but still have just a one-game edge in the loss column over the champs.

They won't play each other again until the conference finals (if they get there), but both the Rockets and Warriors have some interesting road games this week. Houston will visit Oklahoma City and Toronto, while Golden State will visit Portland (where the Blazers have won 13 of their last 14) and Minnesota.

Dig into some of the key numbers from this week's Power Rankings.

Hero team of the week: Houston (3-0) -- The Rockets' week included two double-digit, road wins over teams - the Clippers and Jazz - that have otherwise been playing well.

Team to watch in Week 21: Houston -- The Rockets take their 15-game winning streak on a four-game trip, which includes three games against teams with winning records. The highlight should be their Friday game in Toronto, where the Raptors have the league's best home record.
