The Celtics are interested in C.J. Watson but the Nets don't want to part with him, sources told Adrian Wojnarowski of Yahoo! Sports. It appears the Nets have been fairly active in trade talks thus far, but they only seem willing to part with spare parts Kris Humphries and MarShon Brooks. We're not sure how far that will get them, but we also can't imagine Watson would bring enough back to make dealing him worth it consider Deron Williams' failing health.
