I agree 110 percent with this. McDermott is too conservative to have cutting edge game plans. Cutting edge plays, are an unknown result, he wants to stay with the higher probability known results, thus why most of the NFL teams never talk about not being surprised by the scheme of the Bills. Unlike the example of our last offensive play vs the Chiefs last year in the playoffs, where we were completely caught off guard.
We need a mix of high probability, sprinkle in a dose of cutting edge to help keep other teams honest.
Hopefully we are saving this for the playoffs.
