Don't really have problem with what kap did. Like it or not he has a right to protest. You can argue he shouldn't have done it at a game but that's about it. If he gets blacklisted over this thats bullshit.
Kaep's completely right
He has every right to be mad and take the actions he did. My belief is though he is doing this for an entirely different and wrong reason. All reports this off season have been how bad he has looked, having a dead arm and having issues with the NIners front office. I feel he is doing this to try and force the Niners hand, release him and if no one signs him he can say he is being out casted from the league because of it.
Remember this gem from last year:
