In honor of this weekend's Duke and North Carolina showdown let's take a look at college basketball's top rivalries:

1. NORTH CAROLINA/DUKE
No other rivalry on the list year in year out has so much on the line. More often than not the team that takes the season advantage gets consideration for a No. 1 seed in the NCAA tournament.

2. KENTUCKY/LOUISVILLE
Basketball is king in the Commonwealth and you are not allowed to root for both teams. There are still some Kentucky fans that hope Rick Pitino burns in hell for taking a job with rival Louisville.

3. KANSAS/MISSOURI
There are more people in Missouri that hate Kansas than there are the Cubs, Broncos, and Raiders combined.

4. INDIANA/PURDUE
It's not quite the same without Bob Knight and Gene Keady on the sidelines, but no there is no state where basketball is taken as seriously as it is in the Hoosier state.

5. CINCINNATI/XAVIER
These schools are 10 minutes apart and you can throw out the records when they meet up as no matter what the scenario this annual match-up generally goes down to the wire.

6. ARIZONA/UCLA
The Pac-10 offers some good candidates for the list, but no two teams have enjoyed the long-term success that the Bruins and Wildcats have managed, making their rivalry even more special.

7. THE BIG FIVE (La Salle, Pennsylvania, St. Joseph's, Temple, and Villanova)
While this unique pentagonal rivalry does not have the same national impact as the previous four, the history and intensity matches it without question. St. Joe's, Temple, and Villanova have all had their moments on the national stage in the last 20 years.

8. UCONN/TENNESSEE (Women's)
The fact that I even included a Women's College Basketball rivalry on the list speaks magnitudes for how special of run that these two schools have enjoyed and how much they typically stand in each other's way to a title.

9. TEXAS/TEXAS A&M
Texas is known for its football, but don't tell these two schools. It almost looks like a football game when the Longhorns tangle with the Aggies on the hardwood as the game always promises to be physical.

10. PENN/PRINCETON
Ivy League basketball is often overlooked, but these two teams never should be. There games are always nail-biters and it seems like every year which ever school prevails ends up a Cinderella candidate once the Dance begins.
