A fair question, I see it hasn't been answered yet.
Your assumption, and it's a huge one, is that Claeys would have won 9 games again this year. And beaten every team that he beat last year.
tbf Claeys probably would have kept most of our o-line, our corners would be much more comfortable in Johnson's defense, and none of our players would be suspended for pot so it's not an unfair assumption to say that we would probably be better this year with the Claeys and the Johnsons at the helm.
I will always be curious as to how the Seth Green experiment would have ended up.
Hell, I'm watching Wake Forest games this year because I miss our defense so much.
