I'd argue that FSU-Miami ought to be on this list, but maybe the fact that it only really goes back 15 years or so reduces it some. Anyway, here's a couple of the college football rivalries that made the list, along with a link:
Unrivaled: The 20 top sports rivalries:
"Oklahoma-Nebraska: The game of last century is considered to be the 1971 meeting between these schools when both entered 10-0. Nebraska was ranked No. 1 and the Sooners No. 2. Johnny Rodgers starred as Nebraska prevailed 35-31 and went on to defeat Alabama for the national championship in the Orange Bowl. New Cornhuskers coach Bill Callahan, a South Side native, has some work to do to maintain national interest, especially considering they don't meet every year anymore with the Big 12 divided by North and South divisions.
Florida-Georgia: The world's largest outdoor cocktail party is held every fall in Jacksonville at Alltell Stadium, formerly the Gator Bowl. Lindsay Scott caught a 93-yard touchdown pass in the 1980 meeting to help the Bulldogs to a comeback victory on the way to the national championship. The Gators dominated with the arrival of Steve Spurrier, and Georgia still is fighting to turn the tide."
[EDIT] Whoops, I spoke too soon. There's a list of "new" rivalries (the two listed above were in the "Old" section), and FSU-Miami makes the cut there. See the link.
