While the NFL and NFL Players Association seem on track to strike a deal hammering out the details of playing football during COVID-19, a rift is brewing amid the players that could hinder the ability to come to an agreement.

According to Pro Football Talk's Mike Florio, players on fully-guaranteed deals (in other words: stars) want all of their money in the case that games are cancelled, while players on non-guaranteed contracts are set to lose money with cancelled games.

“It’s splitting the have’s and have-not’s,” one source told Florio, while another said a “brawl” could be coming between the stars and the rest of the players.

As Florio notes, the vast majority of players—basically, everybody who isn't a star early into a veteran contract—are on non-guaranteed deals, including most members of NFLPA leadership. If a majority vote happens on the Executive Committee, players with guaranteed salaries would not receive full pay in the event that games aren't played due to the pandemic.

If the players on guaranteed deals feel wronged by the new NFL-NFLPA agreement, they could explore leaving the players union and/or pursuing litigation. In some cases, players opted for guaranteed salary over other bonuses when they inked their deals, in order to help team with salary cap or cash relief. For those players, it's understandable to be irked about missing out on money for going the team-friendly route.

But, again, that contingent of stars, including Dak Prescott and Aaron Rodgers, likely won't illicit a ton of sympathy from their peers on non-guaranteed deals.

The players will have to reach some kind of accord before the NFL and NFLPA can be finalize an agreement for the 2020 season.
