Having seen this video before I understand that while Dalton is not a horrible option, just that Fields is the better option in my opinion. Now that camp has opened I think Fields will make it tough on Nagy to not alter his plan.
Hope that's the case but I don't have issue with Dalton starting the year for a couple reasons. My concern is that Nagy is too stubborn to adjust his plan if Fields proves to further along than he has any right to be.
It's a catch 22. If the line proves viable, Dalton should also be but if it's not, Fields would clearly do better early but at the same time not be able to stay in the O and progress as quickly as hoped.
From wiki:
Dalton is one of ten quarterbacks in NFL history to have thrown for over 3,000 yards in each of his first three seasons and one of only six to throw at least 20 touchdowns over the same span.
He was the 35th pick. He's plenty aggressive and competent enough but if he gets pressured, he will try and make something happen and fail.
