Very true. As also they will push that roster increase. More games, mean more injuries. So they need more players. Maybe not so much as to game day limits, as that most likely would stay at 45. But an increase in the roster, and maybe have more inactives.
I doubt they would bring back a limited form of IR to keep players [as when they use to stash players for the future, putting them on IR for a hangnail]. Maybe more practice squad players, but you can protect so many of them from leaving to other teams.
I think it will be a while to work all that out. Also depends on any TV contract negotiations, to get more money for the owners, to pay the extra pay.
