Well, actually, the remains of the reserve system do make a player's labor the property of the team for six years (though 3 or 4 of the years are subject to arbitration). Of course, no one technically has to play Major League Baseball, but realistically it will be the best option for almost any player (maybe in a handful of AAAA cases Japan would be better). So, to the extent most players are concerned, MLB has an effective monopoly on pro baseball and dramatically limits the labor freedom of the players. For those subject to the draft, they really can't choose what team to play for. Then, the hurdle to reach free agency (other than stinking and getting cut) is extremely high- 6 years. The average career is what, less than 2 years? And once a player is on a 40-man roster, even getting cut often doesn't lead to free agency, because the team first waives the player, who can then be picked up by another club (again the player has zero say over any of this). So, putting aside the fact it's literally insane to say Bremer was being racist, and in fact only reveals something about the person making the insane accusation, the term "property" is actually pretty appropriate for the team-player relationship in most cases.
