It is not hypocrisy.

Say in the NFL a group of players started advocating for a change in rules. Say, they want a rule where a player must be evaluated and sit out of a game after taking so many hits of so many g forces to the head.

If certain teams decide to implement the rules unilaterally it would put them at a disadvantage. The rules have to change for everyone for it to make sense. It is perfectly reasonable for a team or player to advocate for a rule change without acting as if that rule is in place without a hint of hypocrisy.
