I hope the negotiators and advisers look beyond the bare percentage going to the players, and also look at the income sources that make up the calculation, what the owners do with their shares of the income etc. A slightly lower percentage of a much larger pot can make the players even more wealthy. The owners have claimed that they need a higher percentage to fund stadium improvements and other things that improve the overall business. I understand that some but not all of those things go to players, but some clearly do with bigger better stadiums.
The players may be faced with a decision about trust in the owners ability to continually increase the overall business, and would they rather have 59% of $9 billion or 57% of $10 billion. Taking a lower percentage might result in more money in their pockets, if the owner really can use the extra money to increase overall income as they have suggested they have and can.
