Most if not all of us are employees somewhere, so we can naturally see/agree with the player's POV, but the owners will always have the leverage. For one thing, if the players get their way and get a prorated salary in 2020 rather than 50/50 revenue split, will the MLBPA complain when owners don't spend money on players in 2021?Because that will ultimately happen. With so many teams losing out on revenue, there will be a tornado of non tenders, and lack of spending on free agents this winter. Of course, owners are not obligated to spend money, just as players are not obligated to split revenue. See where this is going? It's not going to end up good for the players.
Players do not move revenue in baseball. Mike Trout can be replaced by Jo Adell for $600k and the Angels (in a normal circumstance) will probably see little to no difference in revenue. Fans cheer for the front of the uniform in baseball. It is a regional sport. That is why it is not as popular in the mainstream. Players are not recognizable, and fan bases are loyal to the franchises. The MLBPA should not die on this hill. Teams will pay for age and performance, so the most important aspect here is to get players to make more money in years 0-6 of service time when the next CBA rolls around. If they piss the owners off for a prorated salary in 2020, it will screw them badly in the end. Of course, both sides appear to want a lockout for some reason based on the way they are acting, so maybe that's their plan all along.
