If that's a straight up trade, I don't think I'd go for it as the other team. And I love Gio. The other guy probably thinks along the same lines I do, and that is you really should have a solid backup QB, because that position is prone to injury, and also the highest scoring position in fantasy. So you want decent quality as an insurance policy. (at least I do) Unless he is really hurting at RB, then yeah, maybe I would.
Now, if you package Dalton in with a RB benchwarmer (Woodhead) then I'd probably be listening.
