The Bills are paying very little for QB's while Josh is on his rookie deal. Dalton is paid cheap starter money but also you'd have to give up a pick for him. Very unlikely IMO as Beane covets his picks for young talent. I don't think it would be crazy for the Bengals to trade their first pick and keep Andy. They can get a boatload for it, they have a lot of needs and I think Dalton is a winner on a good team. I'm sure this comment will generate some criticism but Andy over the next 3 years might be as good as any rookie coming in, even Burrow will take some time to adapt to the NFL.
As for Barkley, he didn't inspire confidence yesterday but to me it points to the need for the Bills to further improve their run game also.
