If they think a uni will enhance performance, I'd refer them to Georgia blackouts and Penn State whiteouts and innumerable other color-outs, that have failed miserably.
They might give an outmanned team a momentary emotional boost. But get dope-slapped the first time, and your uniform that looks more like a jousting flag than a football suit becomes more a joke than a fashion statement.
If the opponent du jour can't deliver the dope-slap, believe me my SEC brethren, there are others who will.
