Josh Smith at the 4 instead of Bargnani
would certainly make us a much better defensive team.
I don't think Atlanta wants anything we'd have to offer, though. Bargnani? No. I think they get a better offer somewhere else, before ever getting that desperate. If J-Smooth is traded, Atlanta is either going full rebuild mode (expiring and picks), or looking to replace him with an all-star calibre player so that they can still have a chance at the playoffs. I don't think the Raps can help them with either plan.
Just my impression/opinion.
