I would have to think Barnes would still have some value. He's our best trade asset. We have a TPE, which could be valuable too.
Barnes really isn't working, he's just not cutting it on this squad. Before teams figure out how poorly he's been playing, I think they should deal him for a valuable bench scorer. Think about it, Green has been better than him so far. Really, I could be wrong and could be a star down the line, but he isn't doing anything for this team now, and with the right piece this team is in serious contention for a title.
Like I said, get a scorer like Stuckey, Turner, Lowry
