The following offensive and defensive players have been so good over the course of the year, but they are no longer considered legitimate candidates to bring home Rookie of the Year honors this season.
Trent Richardson, RB, Cleveland Browns
Richardson has been the focal point of the Browns offense all year long. While he hasn't been as dominant as many expected, he is still having a quality season for Cleveland.
He needs only 50 rushing yards to eclipse 1,000 yards on the season. He'll only get better as time passes and should continue to lead Cleveland for the foreseeable future.
Alfred Morris, RB, Washington Redskins
No rookie has been as undervalued as Morris has for Washington this season. Of course, it is hard to really shine when the other stud rookie on your team is a guy named Robert Griffin III.
However, Morris has been just as effective as Griffin this year, as he's on pace to rush for over 1,500 yards on the season. With Griffin and Morris, the Redskins have quite the core to build around.
Doug Martin, RB, Tampa Bay Buccaneers
While Martin's play has dropped off some in recent weeks, he has still been one of the best offensive rookies this season.
He's been extremely effective in both the run and pass game and already has nearly 1,800 total yards on offense. Unfortunately, the Buccaneers have struggled down the stretch, and Martin's hopes to win Offensive Rookie of the Year are all but over.
Harrison Smith, FS, Minnesota Vikings
Few rookies have been as impressive as Smith has been for the Vikings this year. He's exceeding all expectations this season and proved any doubters about him being a first-round pick completely wrong.
Smith's huge hits and ability as a playmaker have revitalized the Minnesota defense and have them on the verge of making a surprise trip to the playoffs.
Lavonte David, OLB, Tampa Bay Buccaneers
Much like his teammate Martin, David's chances at winning Rookie of the Year are all but gone due to the overall struggles of Tampa Bay.
However, to say David hasn't been exceptional this year would be a major error. He's easily one of the best young linebackers in the game and should anchor Tampa Bay's defense for a long, long time.
