I want no part of Aaron Glenn as a HC

I never claimed Campbell was an X & O guy; my point is that some HCs are more leaders and motivators than Xs&Os. The one benefit of taking over a team that has been losing for a long time is that they have been accumulating talent. That's why the Jets have multiple all-pros on defense. Obviously, having a top-notch GM is critical for any organizational success.
If yrs of loosing is the way to get talent what haven't the Browns and the Bears and the Panthers loaded with talent.
My point is that Campbell is no different than Ogeron was @ LSU , dependant on his OC and DC and a boatload of talent
