NFL owners are pushing to expand the 16-game regular season as part of their new collective bargaining agreement with the players.

The players have shown little interest in the idea.

The players are seeking an increase in their share of revenue in the next CBA, but the owners have indicated that's a non-starter without expanding the season.

The NFL could expand to 17 or 18 games or add an extra round of players. All of these concepts include shortening the preseason, which both sides favor.

The retirement of Andrew Luck has had an effect on the mindset of players as they were already disinclined to expand the season.
