I have been around forever compared to most posters here, or even on the net in general and I tend to be more sentimental on old stuff, but what sports rivalries are your greatest? I know there's a lot of newer stuff that hasn't had to stand the test of history but are no less important. When I meet my old buddies, it's always about Magic Johnson and his Lakers, or Joe Montana and his 49ers, or Muhammad Ali, or how New York stole the A's Reggie Jackson and Coach/manager Billy Martin. While I almost put the Giants-Dodgers, I don't think there's anything I have seen in my life as exciting as Bird vs. Magic. To see them both on the dream team was beyond description. I put in 10 options but could have put a lot more. A lot of the options make top 10 lists but then there are a lot of top 10 things, especially heated college rivalries, that I didn't put here. Honorable mention for me is: Ali-Frazier, Patriots vs Giants, UCLA-USC in almost anything, and 49ers-Cowboys. What made me put in Pacauaio-Marquez over Ali-Frazier is the closeness of the Pacqauio-Marquez fights and some say controversy in splitting hairs which makes for a great rivalry. Had Eli Manning and the NY Giants actually made it to postseason this year, and the Giants and Pats squared off (yet again) in the upcoming Super Bowl, then they would be right at the top of my list. With UCLA and USC, there are just so many sports both schools are great at (UCLA holding more titles than any school in the nation) that I can't do it justice here. There's a perceived middle class student at UCLA vs. rich student at USC rivalry that southern California people all know about similar to a socio-economic divide between Cal and Stanford. And finally the 1990s wasn't complete, and utterly frustrating to a 49ers fan like me without the Cowboys besting the 49ers two out of three times in the NFC championship that many considered the real Super Bowls of the '92, '93, and '94 seasons. Dallas would go on to win both the 1992 and 1993 season Super Bowls and the 49ers took home the 1994 season Super Bowl.
