most players would love a guaranteed $15M and a chance at lucrative free agency after. you know who doesn't? a player that knows he is almost done and wants guaranteed money. the fact that everyone is so concerned with guaranteed money tells me as a GM i would never give it to him. Performance bonuses all day long and big salary yes, but guaranteed?
Bell is holding out because he knows he is almost done. one more nick, one more drug test, one more wrong statement on twitter.......he wants long term money so he can party and relax. no one is giving him this. ever.
why would anyone with half a brain give an RB guaranteed money over multiple years in today's NFL? they don't. only the half brains do. Bell is trying to prove a point on how bad the system is but he is the wrong guy to do so. his market value to smart GM's is waaaaaaaay less than he thinks it is. literally any other position besides kickers would be better off trying this.
the franchise tag seems like it should be illegal and probably goes against the principle of most labor laws but Bell is the complete wrong guy to fight it because it is actually an amazing deal for him. he just is not worth what he thinks he is. not even close. and yes i know he is good at fantasy football but that's not what this is about.
EDIT: not sure why i quoted your post. i agreed with your question.
