Running backs and linebackers are historically the best bets to win the Rookie of the Year.
Since Reuben Mayes won Offensive Rookie of the Year for the Saints in 1986, 17 of the 22 winners have been runners, though three of the past five winners have been non-running backs (Anquan Boldin, Ben Roethlisberger, Vince Young). On defense, a linebacker has won seven of the past Defensive Rookie of the Year awards.
There are plenty of good rookie RB candidates, though linebacker is a bit thin this year. With that in mind, here are some early candidates:
Offense
1. Raiders RB Darren McFadden: Right now, he's the clear favorite, even though Justin Fargas and others figure to get carries. But there's a sense in Oakland that he's the team's best offensive player and could be special in short order.
2. Panthers RB Jonathan Stewart: He still has a painful toe he must overcome, and DeAngelo Williams has had a strong camp and will start. Stewart might not get the majority of the carries, but he will be a big part of the offense nonetheless.
3. Titans RB Chris Johnson: I try not to get too biased based on one highlight, but you can see why the team is excited by his potential when you watch Johnson's 66-yard romp against the Rams. He'll have some highlight plays, but he must prove to be durable and take the big hits.
4. Bills WR James Hardy: The Bills' offense still needs some help in spots, but Hardy has been a strong performer in camp and has shown the ability to run down the field and catch passes in traffic and the red zone. He's big and fast, and if he can keep his nose clean and stay focused, Hardy might be a very good rookie.
5. Lions RB Kevin Smith: All signs point to him starting right away, but all signs point to some tough sledding right away. The Lions' O-line hasn't run-blocked well in the preseason, and the strength of the team remains at wideout. Smith could be a slow starter but a strong finisher.
Others to watch: Falcons QB Matt Ryan; Ravens QB Joe Flacco; Jets TE Dustin Keller; Broncos WR Eddie Royal; 49ers WR Josh Morgan; Redskins WR Malcolm Kelly; Eagles WR DeSean Jackson; Panthers OT Jeff Otah; Broncos OT Ryan Clady; Bears RB Matt Forté; Ravens RB Ray Rice; Cowboys RB Felix Jones
Defense
1. Patriots LB Jerod Mayo: Observers in New England feel there's no way the Patriots can keep him out of the starting lineup, and he'll be in a position to rack up tackles. We might not be talking about a Patrick
Willis-type stats machine here, but on a winning team Mayo should stand up as a favorite.
2. Chiefs DT Glenn Dorsey: He has been hurt so far in camp, but he's a guaranteed starter when healthy and one of the five most talented rookies in the league. If the Chiefs' defense shows marked improvement, many will point to Dorsey's presence as a major reason even if tackles don't rack up big numbers typically.
3. Giants FS Kenny Phillips: They are raving about Phillips' range and closing speed up in Albany, and he should be considered a starter any minute now. Tom Coughlin might not admit it, but he got a steal in the draft. How rare -- and fortunate -- is it to see a Super Bowl winner get a Rookie of the Year candidate this good the next year?
4. Saints DT Sedrick Ellis: Some of the same reasons that Dorsey could get mention in Kansas City certainly apply to Ellis in New Orleans. The Saints' defense is expected t improve, and a division title could go a long way towards getting individual attention for a tackle of Ellis' ability. And vice versa.
5. Bengals LB Keith Rivers: He was a late signee, but Rivers stepped in right away and looked strong against the Packers' second- and third-stringers. Expect Rivers to be an opening-day starter and put up moderately strong numbers on what I think will be a better defense.
Others to watch: Rams DE Chris Long; Seahawks DE Lawrence Jackson; Dolphins DE Kendall Langford; Falcons LB Curtis Lofton; Bills CB Leodis McKelvin; Chiefs CB Brandon Flowers
