This year, certain positions like quarterback, running back and linebacker have seen an influx in rookie talent already playing at a high level. Robert Griffin III, Andrew Luck and Ryan Tannehill have all been impressive as rookie signal callers already outplaying the veterans that were starting on their respective rosters last season.
Every year we see a few rookie running backs tear up the field, this year's crop includes Trent Richardson, Brandon Bolden and Alfred Morris.
Linebacker is typically a very difficult position to learn as a rookie since there's so many different roles in the middle of the defense, but we're already seeing many players like Bobby Wagner, Dont'a Hightower and Mychal Kendricks starting and excelling.
Not all of those players could make our top 10 rookie list and some like the Eagles' Brandon Boykin and Bills left tackle Cordy Glenn just missed the list.
