Uniforms of all players have been made as realistic as possible.  For rookies, I used college equipment, unless I could find a picture of them from training camp (in which case, usually only a helmet has been adjusted).  Therefore, some of the rookies have not been updated with their pro wear.  I'll try to make them as realistic as possible as the season goes on.  I used gettyimages.com and Google Image Search for reference in my research.

Unfortunately, a few things had not been incorporated into the game.  These include team-colored forearm neoprene (like Carlos Emmons or Jason Witten), certain facemask designs (a #5 and #7 combo like Willis McGahee's), long hair that isn't dreadlocked (Dan Campbell, A.J. Hawk, Nick Sorensen), etc.  I tried my best to get the closest approximation.  Player equipment will be in constant flux throughout the season.

Player faces and skin tone have also been changed wherever I noticed that the likeness was way off from what the player actually looks like.
