They call it an owner proposal, but they don’t get to the ratification section unless it’s been agreed to in principal in their negotiations. This isn’t like a budget bill. Owners and player reps have been talking about this off and on for a long time. They’ve agreed to something, the owners have formalized it into this CBA, they’ve ratified, now it goes to the PA who will basically just look to see if there’s any discrepancies between this and what they’ve agreed to, if it matches they send it to the players for general ratification. If this proposal was coming from the owners without the PA having been involved there wouldn’t be a 24 hour turn around. Heck they’re so bought in according to ESPN it’s going to the players regardless of what the PA says, which means the PA is going to say yes.
