In this situation, I would say yes. As a player, you are a representative of your team and the NFL. Your behavior speaks out and reflects on those organizations. As we saw last year, it had a negative impact on the teams and the league, not to mention the players that couldn’t get a good deal following their actions. If you go to work somewhere, they have a set code of conduct, generally. If you violate that code, you are generally punished somehow. No different here. And if you refuse to follow the rules, you can, in the real world, lose your job.
