APPENDIX A
NFL PLAYER CONTRACT
4. PUBLICITY AND NFLPA GROUP LICENSING PROGRAM.
Player will cooperate with the news media, and will participate upon request in reasonable activities to promote the Club and the League.
______________________________________
As shown above, both collective bargaining agreement and player contract language is subjective in how players speak with the media. Any player cannot pull a Marshawn Lynch and not choose not to speak with the media. The players' action would be interpreted as uncooperative and/or cast a negative light on the franchise or the league.
Some players are more than happy to carry on (sometimes lengthy) conversations with the press in order to promote their brand. The players get something back in return for going above board to give media soundbite material. It is a win-win situation.
That said,
no player is forced to make, what is essentially sometimes unnecessarily explicit small talk, with the media. Blathering is a personal choice players make when a camera or microphone is in front of their face. Any implication that any player must talk with the media like it is a non-spontaneous,
Big Brother, reality television moment is patently false.
