Smith + Marvin for Amare seems like a better deal.
I said it before, but I guess I'll say it again. We won't put both Smith and Marvin in the same deal for anyone. Honestly, it'd have to be the "right" piece(s) before we'd put 2 of Smith, Marvin, and Horford in a deal, but we won't trade both Smith and Marvin in any 1 deal.
