For me the question isn't if Dalton is as good or nearly as good as Dak. I really like Dalton, especially as our backup QB but he is not better than Dak. For me, the question is if Dalton is good enough to take us to the SB with what we have. Will our offense be as good as we think it can be? Can our defense be top 10 again? If yes to those questions, I think Dalton is good enough to let Dak walk and spend our money elsewhere. If not, we better keep Dak.
For the record, this team is not proven enough to let Dak walk and roll with Dalton. We have to keep Dak as long as he isn't asking for $40 mil a year.
