Yeah, it's going to be ~50 games and a pill no one will like swallowing.
I don't see an offer getting any better. Manfred has been able to say all along, "The season will be X games long. It will begin on this date. Players will get their normal, prorated pay for those games." The owners have presumably told Manfred the # of games they're willing to pay players their full (prorated) rates, and with no other offer on the table, that # will be the same number of games the players will be okay playing.
The owners have made attempts to get the players to play more games for less than their prorated salaries, which has understandably been a non-starter. Players have made attempts to play more than those X games for their prorated salary, which the owners don't see as a satisfactory alternative, at least in part due to lack of in-park revenue.
The final headaches will be pay and service-time related for players who have objections that go beyond their own individual health issues, and whether some of the agreed-to issues like draft pick compensation and roster size/makeup will remain or be rolled back. Manfred can't make those decisions unilaterally.
