The Man in the Sweater Vest

So, let's talk about the man in the sweater vest. What are we to make of this model of straight-laced propriety? He patrols the hallowed sidelines of the Horseshoe with the air of a great military commander, mowing down foes like Patton and his tanks. But five-star generals never go to war in V-necks and an AT&T headset. And what of the slightly tinted spectacles, neatly trimmed hair and pressed slacks? It says more "professor" than "football coach."
