well rage, you might be right about not knowing exactly what is in a players contract with the team/NFL. but, I am pretty confident that there is language in most contracts that would be similar in content. most of those contracts will not allow certain acts, especially in the official capacity of the execution of that said contract. if the act is a "political" act in uniform, on game day, that can be perceived as a political statement and could apply to that language if present. Then if it is present, then yes, I believe, that it can be construed as a violation of that type of language if it does in fact exist. The question of whether it does exist is also no so much in doubt in my mind, as we hear about players being punished, banned, fined or what ever for acts when they are not even in uniform let alone on the field.
