This is WAY more common than you think. Especially with contract work. it is ridiculous to show so much of your books. They seemed to have given up a lot already, and what good would records from 10 years ago be? It is a different economy now and it will change in the future, which both sides are forgetting. Want to see jerry jones's book? He is has a 2 billion dollar expense for a crazy stadium he made to "improve the game." This game cost a lot of money now.
And the owners opening their books to the players? Ya.... that worked out REALLY well for the nba. I bet the owners would be stupid enough to show their books if it didn't !@#$ up the nba so much not too long ago.
But as much I hate the players for what they are doing, I am more pissed with the owners. Forget all the things that REALLY need to be fixed in the nfl.... the only thing screwing these negotiations is money, and it should be the least important thing. Even the non millionaire football players make a decent living, even if it is only 3 years, to invest in themselves and have a better start in life than most people. The whole thing is bonkers and both sides are being unreasonable. neither side is worth crying over.
