I'd probably try to get something good for him, but I would hope the AI would not give up too much for a 37 year old player regardless of ratings. I think the AI will probably say he's too old etc.. If I could not get anything good for him I'd keep him of course
. If he wanted too much $$$ I'd let him go to free agency - maybe pick him up very late in the FA draft if he wants a reasonable 1 year deal.
