Black uniforms were worn ONE GAME. It was the Homecoming Game in 1986, Tressel's first season. YSU lost 49-14 against Middle Tennessee. I was at the game, and it was even worse than the score would indicate.
Uniforms were never again worn for anything other than practice.
As for alternate uniforms, where is the money going to come from to pay for these uniforms? The football program already spends alot of money, and based on the programs performance the last 13 seasons, they are not deserving of alternate uniforms. This is YSU, not OSU.
