What schools should play more often? (Semi-regularly)

With the Penn St - Notre Dame semi final game coming up this got me to thinking, the game “feels” like a rivalry despite only playing 19 times (9-9-1). A few that come to mind from my anecdotal experience:

West Virginia vs Virginia Tech (30-23 WVU)

Michigan vs Notre Dame (25-18 Mich)

Florida vs Miami (30-27 UM)

Texas vs Nebraska (10-4 UT)

I know ND and Michigan is already considered a rivalry. What others do y’all think have some angst towards each other despite not playing that much through history?

*** in conclusion, can we all agree having the schedules loaded with little sisters of the poor sucks for the fans? I get it for one game but 3-4 cream puffs is crap. ***
