You telling me you wouldn't complain when your boss hires someone to do your job and won't let you go until they are sure the new guy can take over for you? Crayton can't go find another team to play for until he is released. If the Cowboys hold on to him until the last possible minute it hurts his chances to find another team, learn their system and contribute. If he even finds another team he has to decide if he is going to move his family or just himself to wherever he is going to play next.
Like I said, its not just about the money.
The guy didn't say a word until they drafted someone that is going to take away his time on the field.
