How about reverse the tables and give Dak nothing, and see how he does? The Chiefs took away Patty's top WR and who can even name one of their WR's now, or their starting RB? Burrow got as far as he did this year with a MASH unit on his OL. I will also argue that Dak is in the same boat as Allen is, as the Bills have done everything to have him succeed and his issues are quite similar to Dak's.
The Fish have given Tua plenty of needs on both sides of the ball, and Tua doesn't look to be cut out for the NFL because of his size. Bryce may have the same issues when he gets to the NFL next year because of size. I haven't even mentioned AR, who historically has been given total garbage from ownership, and he has done fairly well for himself.
No doubt Dak needs support to succeed, heck, he was a 4th round pick for a reason
