Some one else mentioned this game.
After that game, I remember thinking: Damn, We have a football team and we did.
From the the vid posting on youtube:
Kentucky's Big Blue Defense, coached by Defensive Coordinator Charlie Bailey, totally dominates Penn State defensively in 1976 and 1977.
Penn State's lone lost in 1977 was to the Big Blue in Happy Valley.
Kentucky in 1976 shut out 3 of its last 4 opponents.
In 1977, the Kentucky defense only allowed 111 points and led in almost every SEC statistical category.
Kentucky recorded 2 shutouts in 1977 against Georgia in Athens, and against Va Tech.
No Kentucky defense since has even come close to the 1977 team.
And this was against a non-SEC schedule against the likes of North Carolina, West Va, Penn State, Baylor, and Va Tech.
Tear away jerseys were outlawed the next year by the NCAA, iirc:
