Among the issues that NFL owners will discuss at next week’s league meetings are proposed rules changes regarding hair covering names on jerseys, radios in defensive players’ helmets and instant replay on field goals.

But the issue that could be the most contentious relates to the size of training camp rosters.

John Clayton of ESPN reports that some teams want to change the current rule, which limits the number of signed players on rosters to 80. Per Clayton, the Tampa Bay Buccaneers have proposed increasing training camp roster limits to 90, the competition committee is pushing for increasing rosters to a maximum of 86, and some owners want to keep the limit at 80.

Part of the issue is that in past years, teams could use roster exemptions for players from NFL Europa/NFL Europe/World League/World League of American Football, and those exemptions allowed teams to have more than 80 players in training camp. Since that league no longer exists, those roster exemptions no longer exist. That means keeping the rules the same would effectively reduce the number of spots on training camp rosters.

But some owners want to reduce the number of spots on training camp rosters. Even though the money paid to those players is not substantial (the last few guys on the training camp roster only make about $1,000 a week), the owners and the players’ union haven’t been seeing eye to eye lately, and the owners might not be in a mood to add even a few thousand dollars to the amount they pay out to players.

A half-dozen extra spots at the bottom of the training camp roster doesn’t sound like a big deal, but the debate surrounding it could be the latest sign of labor unrest in the league.
