1. North Carolina/Duke basketball- This is without a doubt the best rivalry in any sport..almost year in and year out their both good teams, It's great to watch on tv..but you haven' experienced it till you've saw it in person..you have to remember that these two teams are within about 8 minutes of each other..All the great games between these two, the amazing talent they always seem to have..it just doesn't get any better for me..It's an experience when you live in North Carolina, They actually let us watch the ACC tournament in school..I'm a UNC fan BTW..
heh
2. Yankees/Red Sox-One of the best Rivalries to watch because it's like David vs. Goliath..I'm a Red Sox fan and I understand the greatness of this rivalry, I don't care if you hate both teams your going to watch if your a baseball fan..
3. Honorable mentions- Cowboys/49ers, Celtics/Lakers, Miami vs. Florida State(just gonna get better this year, Go Miami!)..
