Thats not hte point. Its that he could sign with anyone in the league. Kinda of tough to lose something just for a 20 game rental (playoffs hopefully as well).
That may be the problem with most of the avaliable trade options out there. Pick your best fit and take a chance. He may be had for a pick, but how low? Maybe even a mid pick + Hauser or something like that? Time for Munce to move up imo.
