This year's NFL rookie class is going to have a greater impact than last year's, which featured the likes of Cam Newton and Von Miller.
The 2012 class has two quarterbacks in Andrew Luck and Robert Griffin III who could outperform the record-setting year by Newton. They might not equal some of Newton's stats, but more wins and better efficiency isn't out of the question.
The 2012 running back class might be one of the better groups in years. Trent Richardson, Doug Martin and David Wilson all could top the 1,000-yard mark. Later-round backs like Isaiah Pead and Ronnie Hillman could also provide good production.
Here are the 21 rookies who will make the greatest immediate impact.
