My take on the negotiations:
The owners are right that a 50-50 split is fair. First, stop saying the players are down from 57 it means nothing. The CBA expired and if the owners wanted to pay 57 they could have simply extended the old deal. The fact is the players aren't coming down from anything because there is no active CBA. It just as easy for the owners to start at 25% and say they come up 25%, it means nothing. What everyone is really talking about is how much they want nothing else. I love when the players said over and over in the news conference, the owners are at 50 we're at 53 lets split the difference. That's a straw man argument. The owners are saying we are at 47 and you are at 53 so lets meet in the middle at 50. None of its really true its all made up. The owners have decided they want 50 and the players have decided they want 53. That is a very wide gulf to jump. In my opinion 50-50 still pays the players a tremendous amount of money, more than they could get anywhere else in the world. I think they should take it.
The players are right to say we might except a BRi deal if the system issues are favorable. The NBA claims the two issues are separate and distinct. According to the NBA, the punitive luxury tax is about competitive balance and the BRI split is about money. This is not true and they know it. If the luxury tax is so punitive nobody will exceed it, salaries will be greatly lowered. The NBA knows this is true but are choosing to ignore it. The fact is the system and BRI all tie together. Players need a method of switching teams and getting paid what they feel they are worth. If the luxury tax prevents movement, players can't get paid their maximum worth and it lowers salaries. I think the players were right to ask the owners to put a pin in the BRI discussion to talk about the system. The owners were wrong to insist on an agreement of 50-50 before even discussing the punitive luxury tax.
