You said the Bills were second in the playoffs in points. Dalton is averaging 29 YPG in the playoffs. I am not the biggest Kincaid fan but I think we can do better, and I bet Beane agrees.
To my eye, as good as Brady has been and as much as it’s hard to find too many faults, I think the Kincaid/Shakir overlap as “slot” players has been too much to figure out for him. They basically have the same role which makes it pretty difficult to scheme around imo. And with our emphasis on running the football and needing an inline TE in which Knox is better suited for, it’s going limit Kincaid a bit.
Where Kincaid would thrive is a more spread offense with Cooper/Coleman on the boundary and both Kincaid and Shakir lined up off the line. Bills don’t wanna seem to do that too much.
