This is a fair and rational take.
What I want to see is that McD has learned how to be an NFL HC, in particular will he modify his defensive game plan based on who the opponent is rather than run the same scheme week after week. You say the team has the confidence of the Patriots (maybe so), but they need the adaptability of the Patriots, especially on defense. Belichick doesn't have a standard scheme, but modifies what he does based on the opponent; I've heard this from a Pats defensive player during a TV segment on that team. I want McD and Frazier to do this, as well as not take their foot off the gas pedal; if they're up by 14, great, now go up by 21. I hope I'm not asking/expecting too much.
