I know what you’re saying and where you are coming from, but I don’t believe LF is the fall guy to save his own job. LF came up with the game plans, play calls, not McD. McD has taken over playcalling numerous times over the last 6 years, especially in the beginning, but he’s made it clear he wants to be involved with the offense and defense as a balanced HC while his coordinators run both squads.
We’ve heard McD say “it starts with me” over and over again. No one outside this MB things McD is micromanaging the defense as the “real” DC or passing blame. Unless this is truly a decision made by LF (and McDs comments make me doubt that), I think McD did what a HC is supposed to do and made a very difficult call. Moving on from a top-5 defensive coordinator will bring backlash, especially given the current social landscape of the country. LF simply isn’t good enough when it matters and the defensive performance in elimination games has been bad enough that warrant a change.
I believe this team respects LF a great deal and the two sides have done each other a favor. I doubt the defense will be elite in 2023, I am curious to see if they are more clutch though.
