NBA Power Rankings: Examining unheralded players on every team

The streak is over, but the Heat's reign atop the Power Rankings is still alive and well.

Miami fell to the short-handed Bulls in Chicago on Wednesday for its first loss in 52 days. The biggest key to Chicago's victory wasn't Joakim Noah or Derrick Rose (both sidelined) or even Luol Deng or Carlos Boozer (both had huge games). Instead, it was a little-known swingman making just his eighth start of the year. Jimmy Butler not only checked LeBron James and Dwyane Wade but he also added 17 points, five assists, four rebounds and a critical three-pointer to help seal the upset.

Butler's been a valuable, albeit unheralded, contributor to the Bulls all season, but he's not the only one making a difference while going largely unnoticed. With that in mind, let's take a look at the most underrated players on each team in this week's Power Rankings.
