Always loved Crash. He gives a hundred percent and very unselfish. No need to force a trade. He will be a useful player on the bench for a few years. If he increases his value and the right deal comes along, then great.
Brooks and Humphries should also be kept until their value goes up. However I don't relish the thought of seeing either of them playing in Boston. I would move Brooks for a late first and Humphries for a second, if the opportunity arises.
