BSR,
Not sure exactly how to get my point out but you keep looking for someone to come up with a in written reason why they are required to represent him and you have arguably refuted everyones attempts to do so. I would ask this if there was something in writing that allowed them to expell him are you sure that is what they would still want to do?
While I refuted many "answers" to my questions that were clearly wrong, I think in the end Illegal Contact gave me the answer I was looking for. According to the NFLPA contract they can't expel members for anything other than non-payment of dues.
I think they should be asking themselves the questions the Patriots and the NFL are asking themselves which is should there have been a better vetting out process to avoid having hired him in the first place. And maybe even set a policy for this type of thing in the future.
The above is really all I am looking for. For too long has the NFLPA has sat idly by while their constituency goes through arrest after arrest. At some point I think they need to look at themselves and ask how they can do better.
