I understand that point, and guaranteeing salaries is probably not the best answer. I don't have the best answer, but I don't scream from the tree tops when a team cuts a player (unless it's one I like, then it's just being a fan) and I don't scream from the tree tops when a player holds out for more money. I could agree the case for both sides, and neither are completely wrong or completely right. However, this is the ONLY leverage a player has.
As a fan I don't like what he is doing, but understanding the business acumen to what is going on I have no issue with him doing it. After this year he could literally haver no income from football. I have said it many times and will continue to say it, the players have to strike while the iron is hot, and X's will never be as hot as it is right now.
