Since it was unofficially admitted as a member of the ACC in November of 2012, Louisville has been propped up fans and media alike as an Atlantic Division "rival" of league powerhouses Florida State and Clemson. The Cardinals were supposed to tip the balance of power in the conference even farther away from the Coastal Division, and set up an exciting year in, year out three-horse race in which UofL traded blows back-and-forth with the Seminoles and Tigers.
Here's the thing about rivalries: unless you're Wile E. Coyote or The Foot Clan, you actually need to win a couple of times in order to sustain your status as a capable foe.
