I could actually see the Jazz brass going for him, afterall there was the rumor that they discussed Millsap for Ryan Anderson. Bargnani is similar to Anderson in terms of offense, but I don't know if I would trade Jefferson or Millsap straight up for him, whereas I might for Anderson.
I've actually posted on here before that Toronto should get Boozer (which should be doable) to pair with Bargnani. Boozer, Bargnani, and Lowry could be the poor man's version of Boozer, Memo, and DWill, which could be enough to get Toronto into the playoffs as a 7 or 8 seed. I think all it would take is Calderon + Kleiza or Amir Johnson. Works out for both the Bulls and Raptors.
