The Chiefs are going up against their arch nemesis in the Oakland Raiders today.  It has lost its lackluster appeal in recent years due to both teams sucking it up.  However, I still consider it one of the great rivalries in sports.  It got me thinking what are the all time greatest rivalries in sports history.  I ranked them from 1 to 5.  Give me your list and your opinion on what the greatest rivalries are in sports. 

5.  Jack Nicholous vs. Arnold Palmer

4.  Ohio St. vs. Michigan

3.  NY Yankees vs. Boston Red Sox

2.  Celtics vs. Lakers
