Scab Story: The 1987 NFL Strike
You're just looking at things the wrong way. The new CBA benefits most players(probably around 100-150 players really get screwed) and the rank-and-file players benefit WAY more.
What's going to happen is if the elite players are successful killing this deal, the owners will lock the players out in 2021, the players will fold like they always do and they'll agree to
AT BEST the same deal or much likely, a worse deal.
Why go through the charade?
