Potentially = with a possibility of becoming actual
Remove the exemption, and the possibility of being illegal becomes actual.
I stand by my original comment. Just because you didn't understand it, doesn't mean it was wrong. Thanks for playing.
Like many web dullards you rely on condescension, being devoid of critical thinking and rhetorical skills. Killing a human being is potentially a crime. Homicide, a crime, is illegal. Justifiable homicide, not a crime, is both legal and not illegal. Justifiable homicide is not potentially illegal, homicide is not potentially legal, and neither is potentially the other. Killing a human is potentially both. This is not a terribly subtle but seemingly it eludes you. Write back when you've worked it out.
Can't treat this like it's a permanent condition. The anti-trust exemption for pro sports isn't set in stone, and if anything it's moving in the direction Foad advocates. And it is logical that the legality of the court-permitted monopoly would be increasingly questioned, over time, when baseball's business activities have expanded since the '20s from from being a regional entertainment provider to the current international media conglomerate and IP licensing behemoth it is now. There's a pattern in the decisions that show the issue will come to a head sooner or later...
Federal Baseball Club v. NL (1922) 9 - 0
Toolson v Yankees (1953) 7 - 2
Kurt Flood v Kuhn (1972) 6-3 With Powell recusing himself because he owned stock in Budweiser, owner of the Cardinals.
And the dissents in the Flood case, were notable both by their authors (Brennan, Douglas, Marshall) and their common sense approach to the issue.
"Baseball is today big business that is packaged with beer, with broadcasting, and with other industries. The beneficiaries of the Federal Baseball Club decision are not the Babe Ruths, Ty Cobbs, and Lou Gehrigs. [it is the owners, and].. a contract which forbids anyone to practice his calling is commonly called an unreasonable restraint of trade".
No doubt there are more than a few justices who would be receptive to that argument now. So to say it's a settled issue wouldn't be accurate.
