There's little debate among Louisville fans that UK is the #1 rival and Cincinnati is #2
There is more debate on who is #3. Even though we've only played once in 7 years, I still think Memphis qualifies. They were arguably our most heated basketball rival in the Metro Conference and C-USA days.
For the Big east era our biggest opponents are generally West Virginia, Marquette, Pittsburgh, and Syracuse (although we own the Orange, 7 wins in a row on the hardwood and 3 on gridiron)
Who in your opinion is the Cards 3rd biggest foe?
