Frankly, I think it's odd for people to be on the side of the billionaires raking in the profits on the backs of a bunch of young men willing to sacrifice their long-term physical (and likely mental) health to become rich but nowhere near as rich as the owners.
The players are gladiators competing for our entertainment. They deserve to get paid what they're worth. They're the ones putting everything on the line.
Well like the real world says if you don't like the conditions your in go find another job. Without the owners there is no league and blaming owners and fans for sacrificing their health is their own doing no one is forcing them to do it.
