With the first month of the 2014 NFL season in the books, every team has had a chance to evaluate how its roster stacks up and where its rookies can fit into game plans as first-year players.

Some rookies, like Minnesota Vikings quarterback Teddy Bridgewater and Jacksonville Jaguars quarterback Blake Bortles, just started taking on bigger roles in Week 4. Others, like Baltimore Ravens linebacker C.J. Mosley and Carolina Panthers wide receiver Kelvin Benjamin, have been crucial players for their teams throughout the season’s first quadrant.

Each week here at Bleacher Report, I rank the top 50 rookies overall and top five at each position. The players are ranked based upon their cumulative performances for the regular season.

Not every rookie had an opportunity to play this past week, as six teams had their bye weeks. Players who did not play because their teams had the week off were not penalized in assembling the rankings, but might have moved up or down depending on how the players who were on the field performed in Week 4.

There will still be plenty of movement to come among the hierarchy of the rookie class, as we’re still at an early stage of the season where there’s a fine line to balance between quality of individual performances and the size of each player’s sample of games played.

For now, the players who have consistently performed at a high level through their first three or four games receive the most credit.
