Optimism is waning after four consecutive days of negotiations between NFL owners and players and was described as trending "backwards," player sources told ESPN.
Player sources said owners have reneged on a simplified formula that would have given players 48 percent of all revenue.
Player sources reaffirmed a setback in talks occurred when owners last week went "retro" on the formula that will divide the estimated $9.3 billion in annual revenue. The players believed the two sides had reached an understanding on a simplified formula in which they would receive 48 percent of revenue, sources say owners reintroduced their previous formula by asking for $400 million to $500 million in expenses as credit off the top.
Players calculate that under the owners' proposal, it would leave them with approximately with a 45 percent take on revenue, an "unacceptable" amount that one player source said "sets us back to March 11 ... before the lockout."
A management source said the owners have not reneged on any revenue split, claiming "it's a negotiation, which is always subject to change"
A league source said the owners were more flexible Thursday afternoon on the revenue-split formula and maintained the theme "negotiations are negotiations."
Player sources contend the owners' terms changed when the two sides convened a day after owners met June 21 in Chicago. A source said the players went into Thursday's negotiating session with owners at the table, hoping to "get them back on track. They wouldn't move. It's disappointing."
