The NFL and the NFLPA recently agreed to a new CBA just before the league shut down all business practices at team facilities. That new deal includes several increases to team rosters but under the current health situation, another increase may be smart.
Under the new CBA, teams can carry two more active players on their game-day rosters provided they have at minimum, eight, offensive lineman. If they do, they can carry 48 active for games, if they don’t they can carry 47. It really is an odd part of the rule but clearly the league wants to less offensive lineman sitting on the inactive list.
