Apparently, the deal currently put forth by the league includes a hard floor of $180 million (with a cap of $258 million).
That's a quite an increase for the teams at the bottom of the league. We'd basically have to double our payroll to meet it. To ratify a CBA the league needs a supermajority (75%) which means at least 23 of the 30 owners to ratify. Could be tough to find a deal that both the players and 75% of owners (particularly the cheapo owners who like being able to not spend) will agree to. But, if the league does manage to thread that needle and the owners vote for a hard floor, it's more evidence of what we already know - that the small market owners who have been crying poor for years, DeWitts included, are full of it. There is some speculation that installing a salary cap will lead to a huge increase in franchise valuations (the security of having the cap going forward is quite valuable), so maybe that plus the floor will incentivize some of the tightwad owners to vote in favor so they can cash in and sell to better owners.
I think they'll need to do some other stuff to appease the players to get it done. They'll probably have to reduce the time to arbitration and free agency, which ultimately makes sense with the hard floor. It gives smaller market teams an easy way to get to the floor by locking down promising young players. They may have to offer a higher revenue split too.
