Here are the player reps for each AFC North team, according to the NFLPA:
Skinny: Mason is one of the most experienced and outspoken players on the Ravens. Therefore he fits great in this role. Carr and Birk are also two great alternatives from Baltimore.
Skinny: This trio comprises Cincinnati's locker room leaders. Whitworth has taken an increased role and is usually the one who briefs the rest of the Bengals on player issues. Williams and Kelly are both elder statesmen and combine for 25 years of NFL experience.
Skinny: Lately the Browns have been a strange team when it comes to union reps. With three regime changes the past few years, it's been a rotating door. Royal was recently released by the Browns, meaning Cleveland will have another player rep next season. All the alternatives spent their first year with the Browns in 2010.
Skinny: Like Mason, Clark is never afraid to speak his mind. He recently had a lot to say on the pending NFL lockout during Super Bowl week. Randle El and Starks are both intelligent alternatives, as well.
