If Joe Johnson gets paid $15m/year and the owners are short of 57% by $100m, they have to pay the players $100m at the end of the year.
If the owners instead pay Joe Johnson $20m/year, assuming everything else is the same, they are short of 57% by $95m. So they have to pay $95m.
Guess what, no matter what they have to pay the $100m. So if your player is unhappy and wants to leave, you'd rather spend the money, THAT YOU HAVE TO SPEND ANYWAYS.
If you don't understand the logic, you don't understand the system. No offense to anyone, but it's humorous reading some of these comments that make absolutely no sense.
