You need to get away from the 'blame/fault' angle. Dak played really well, he just comes up short against the elite. This O-Line isnt going to improve any time soon: Tyron/Martin age deterioration, Biadazs - FA and Steele - injury (whether he'll improve?) , add in the CAP restraints with the forthcoming CeeDee and Micah contracts and this is as good as it gets for him.
Sometimes very good just doesnt get you over the line, it's not blame, it's just the situation he's in juxtaposition, he needs weapons but his contract demands (and defered payments) means we havent to CAP to facilitate.
