Beginning in 2013, the NFL will have the option of hiring a to-be-determined number of full-time officials to work year-round, including on the field. The NFL will have the option to hire additional officials for training and development and assign them to work NFL games.

so has the NFl hired any year round refs to work on rules, rule interpretation and player safety?
a google only brings up headlines of "nfl hires first full-time female referee". Not sure if that means year round or not ...

^^^ kinda interesting site. i know there is a MLB site where they have ump recaps of games and all the commentators are like high school umps and they talk and argue about refs like fans talk and argue about the actual teams/games. pretty damn funny. taken very seriously.
