It's moronic that both sides haven't even bothered to truly negotiate in good faith yet. As for which side is "right or wrong", they're both wrong. There's no way that if the owners get the reduction in player salaries that they desire will they be passing the savings along to the fans via cheaper tickets. The players are living the dream. I admit that they have to work hard, and pretty much have to give up their lives from since they were children till they are 35, but they get to win the lottery every year!! Maybe they should all take a few years off and see how the rest of the population to get by these days.
As for who should make concessions to get a deal done, I believe it should mostly be the players. They made off like bandits with this expiring CBA, and now it's time to correct the market.
My proposal - 50/50 revenue split, luxury tax, cap contracts at 5-6 years with compensation equally paid throughout contract.
