I want no part of Aaron Glenn as a HC

Exactly - This aint "one game"

This is a home playoff game as the number one seed against a (very talented but) rookie QB... You're a SB favorite that won a division that sent 3 teams to the playoffs.

And they may 50 burger you...

There's red flags... and then there's this.

I find it interesting that you say that because Dann Quinn, the guy whose team is about to head to the NFC Championship game with a rookie QB, is also the HC that blew a 28-3 lead in the Super Bowl. That "ain't one game" and yet it was one game and he's clearly still a very good head coach despite having a horrible game on the biggest stage and in the biggest game of his career.

Is blowing a 28-3 lead in the Super Bowl a red flag?
