Notes
I would point out, however, that just because final scoreboard numbers show something doesn't really tell us a lot (in some cases) about how competitive the game was.
In 1982, we trailed Southern Miss in BDS by scores of 28-7 and 35-14......if you look at the final margin of 9 points, it doesn't look so bad. The same is true in the opposite direction of the 1982 Penn State game. Yes, we beat them 42-21 on the scoreboard, but with maybe five minutes or so left, we led by six. They tried a punt, and it hit their own blocker (he retreated too far back) and we got the ball at their ten and scored and then we picked off a desperate heave by Blackledge and ran it close and scored to put the game away.
Even the 2006 Florida score is deceptive because we were only down by eight with about six minutes left when JP Wilson threw a pick six.
Just for a few points of comparison....post-1969 (when I was born)
