Meh. It's so low energy to just look at W/L on some eternally crappy team and think a guy can't coach because of that. The Ravens owner gave a very transparent presser after firing Harbaugh in which he went on a tangent explaining exactly this as it relates to their coaching search. He was asked what would exclude a candidate and ended up saying he didn't know but that a losing record won't exclude someone.
He is specifically paying extra attention to guys who were hot candidates in their cycle, but maybe landed with a difficult job where they didn't end up winning. His point was that he doesn't think Baltimore is a difficult job, he thinks it's the best job, and might be a better fit for those candidates. I think GB would be similar.
Flores is a defensive minded coach and he did take Miami from 32nd to 6th from year 1 to year 2.
They were 5-11, 10-6, and 9-8 with Tua and Ryan Fitzpatrick.
I don't think that's enough of a shake to know whether or not he can be an effective HC.
But here is the real kicker for me. Every Packers hire I have lived through besides Mike Sherman was done with the intent that the QB had to developed.
Holmgren, McCarthy, LaFleur. That's not a pressing need. I would love to flip the script and get a HC whose emphasis is defense and details.
