The most comprehensive set of weekly power rankings anywhere on the web now moves to the rookies, as we look at our top offensive and defensive first-year players.

Offensive Rookie Power Rankings

1. Odell Beckham, New York Giants

Odell Beckham may not have the stats of some of fellow rookies Mike Evans and Kelvin Benjamin, but he’s by far the better wide receiver. Beckham is already an elite route runner, possesses game-breaking speed and his jersey is already in the Hall of Fame due to his catch a few weeks ago on Sunday night. Beckham is only the second rookie to have over 700 yards in a six-game span.

2. Mike Evans, Tampa Bay Buccaneers

Mike Evans caught a pair of touchdowns in Sunday’s loss, giving him 10 on the season. Evans is also closing in on 1,000 yards for the season as he’s just 65 yards away. Evans wins jump balls and his numbers have been especially impressive considering the lackluster quarterback play he’s had to endure.

3. Kelvin Benjamin, Carolina Panthers

Kelvin Benjamin has proven himself as a big play threat as he has nine touchdowns on the season. The lack of other targets around him has had defenses keying on him in recent weeks, which has caused a decline in his numbers.

Defensive Rookie Power Rankings

1. Aaron Donald, St. Louis Rams

Aaron Donald has become a fixture in the middle of the Rams’ defense and St. Louis posted their second straight shutout on Sunday against the Washington Redskins. Donald leads all rookies in sacks with seven, and he registered another sack on Sunday, giving him five sacks in the last six games.

2. C.J. Mosley, Baltimore Ravens

C.J. Mosley’s impact on the Ravens’ defense can’t be felt solely from the stat sheet, but he is putting up impressive numbers. Mosley is fifth in the NFL in tackles (113) and had a big game in the Ravens’ victory over the Dolphins on Sunday. Mosley had eight tackles and a big sack of Ryan Tannehill, as Baltimore looks poised for their playoff run.

3. Chris Borland, San Francisco 49ers

Chris Borland had some enormous shoes to fill when he was forced into action when Patrick Willis was lost for the season. The undersized rookie from Wisconsin is always around the football and he’s tallied 101 tackles on the season despite starting for just seven games. Borland has also been solid in coverage as he has five passes defensed and a pair of interceptions.
