Ryan Clark updates his NFL power rankings for the Steelers and Titans after their Week 4 performances. (0:31)

Calvin Ridley followed his three-touchdown breakout game in Week 3 with two more scores in Week 4, thrusting him squarely in the much-too-early conversation for Offensive Rookie of the Year. He'll surely have plenty of competition for the award.

As we run through Week 5 of the Power Rankings, we're spotlighting the rookie for each team who has played the most and sizing up the impact he has made.

How we rank the teams: Our power panel -- a group of more than 80 writers, editors and TV personalities -- evaluated how all 32 teams stack up through the first four weeks of the season.
