First of all, considering the massive revenue the NBA gets, I don't believe for a moment that the owners can't break even on 43%. Second of all, why, given the business practices we've seen in recent years to decades, why would any of you actually believe the figures the owners give? They are almost certainly riddled with lies. But the main point is, sports is about athletes. They should make the bulk of the money, period. That should be the assumption going in. I think the split should be increased to 60% for the players. I wouldn't give one fig for an NBA game were it not for the athletes. Not one fig. I wouldn't give a booger. The athletes are the heart of this whole thing. Pay 'em and work from there.
Well, first of all, breaking even is not a good business model. I know we like to think this is just a hobby, but it is still a business, and when they are making their business plans, the goal needs to be to make money.
As for sports being about athletes, you are correct. But the same as any business, someone needs to put up the capital, effort, and know-how to translate that talent into cash. That is what owners do, and they need to be compensated for it, just like the players do.
And finally, you are right that it is tough to believe that the league on the whole can't break even at 43%. And there are teams that are absolutely making money at that number. The problem is, there is a huge disparity in the amount of revenue between teams in different markets. While some teams are able to make money while paying $80 million in salaries and luxury tax, other teams are hemoraging money at $60 million in salary.
And since Basketball is not a sport like baseball, where you can really compete with just young, cheap players (and the players would never agree to a baseball-like rookie structure, which is what allows baseball to deal with their cap-less structure), they need to either share more money (which is going to take a long time for them to agree to), or they are going to need to lower the cap to a number that works for the small markets, not just the bigger ones.
