Cobbs played a huge (very much unsung) role in the 1987 Fiesta Bowl Game win over Miami. He contributed to the massive number of turnovers (but then again, who didn't that night?) and was in on some key tackles.
In Tom Callahan's January 12, 1987 article, chronicling the game for Time Magazine, Duffy was quoted, saying:
"Every play," Cobbs said, "it seemed Vinny was staring me right in the eyes. We'd be faking a man-to-man coverage and I'd be saying to myself, 'I hope he believes it, I hope he believes it.' He'd chuckle just before the snap, and we'd all think, 'Good,' and switch to a zone."
We loved him - at the Blue/White games he was always on our list(s) for autographs.
Duffy made an effort to try out for the pros - he was on the New England Patriots' roster in 1987.
