I have and it's mediocre. That's the reason to question Glenn as the next HC, not one game of sheetty defense.
Although I will say that Glenn said that he will not be calling the defense if he gets a HC job. Maybe he will be a good HC if he hires a good DC who will call the defense. He does seem to have the leadership skills you want, but I don't think his X's and O's are good enough to name him HC. He's more or less Rizzi if he's not going to call the defense and if he's not great on one side of the ball.
