The thing that sucks is that if he plays like crap, we lose him, but if he plays really well, we'll also probably lose him as his contract demands will be high. Either way, he probably won't be a Bill after this coming season.
That said, why cut him? We don't really gain anything, so might as well keep him and see what happens.
EDIT: Darn, MBD beat me to the punch.
