Posting goofy absolutes is just bad form.
Harbaugh was a good NFL coach coming in from Stanford.
But the reality is generally it is awful teams hiring new head coaches and they fail regardless of where they come from.
Matt Rhule is a good head coach and an NFL style program builder, but he tears it all down first and the NFL you better get a QB.
He never stood a chance.
Lincoln's best asset is he develops QBs.
He's only coached Kyler, Jalen, Baker and now the obvious 1st overall next year.
And in the NFL you better get QB right.
I think Brian Daboll is a really good coach but he is likely getting fired because of Danny Dimes and loss fatigue.
The NFL takes freely and widely from the college game which takes freely and widely from High School and then the reverse filters down.
Good is good and it can promote up.
NFL assistants fail at shocking rates too.
The top 5-6 guys stay in place a decade plus and everything else is a flush cycle.
