NBA power rankings 2012: Cleveland Cavaliers sit at No. 25 after rough start

The Cleveland Cavaliers come in at No. 25 in SB Nation's latest NBA power rankings after losing three of four games this past week.

The Cavaliers are 2-5 on the season and in the midst of an unfriendly six-game road trip, which has given them only one win so far. Kyrie Irving, Dion Waiters and Anderson Varejao have been a bright spot in an otherwise disappointing start to the season. Irving is averaging 22.9 points and 6.3 assists per game, while Waiters has tallied 15.4 points per game himself. Varejao has been a force on the glass, averaging 13 rebounds per game and scoring close to 13 points per game while shooting at a 55-percent clip.

Seth Rosenthal writes in the power rankings that the starters, especially Irving, have been fine. It's the lack of production from the bench that has the Cavs at No. 25.

The Cavs' bench is as awful as Kyrie Irving is wonderful and Kyrie Irving is EXTREMELY wonderful.

At the top of the list, the San Antonio Spurs, New York Knicks and Memphis Grizzlies make up the top three teams in the rankings. The entire power rankings can be seen here.
