I was 15 in 1992, and at that point we had an 8 game, 15-7 lead in the series, and had just won 2 out 3 games played in 3 consecutive years. Since 1992 Florida has shifted the series to an equal 8 game lead for them. I'm 41 now, I don't remember the last time I got carded but I ain't quite AARP age yet either. I've seen this shift occur in my lifetime and I am enough of a college football historian generally to know that swings like this one are hardly unique, even in the context of great rivalries, and that's what I said "ebbed and flowed", i.e. many of the great historic rivalries.
Michigan, for example has beaten Ohio State 8 times since 1992 (whereas we have beaten Florida 5). Most of our wins against Florida are more recent than Michigan's wins against Ohio State. Tennessee has beaten Florida 4 times since 2000, whereas Michigan has only beaten Ohio State on 2 occasions since 2000 and yet I don't think anyone would dispute that Michigan and Ohio State is a great rivalry. Yeah, Florida has gotten the better of us for a while, no one has denied that, but it is not some foregone conclusion that the tide will not and cannot turn back in our favor.
Florida is not some unbeatable behemoth, they've had a good run since they hired Spurrier (not so much the last 10 years though), however as I pointed out, they were once perennial cellar dwellers for about 6 decades, and they can return to the depths from whence they came.
