I know the list is a joke and all; but I can think of almost a dozen rivalries than have far more national relevance and interest than Pitt-WVU.
Florida - UGAy
Florida - f$u
ND - Michigan
ND - USCw
Texas - Texas A&M
(hasn't been played in awhile, but it'll come back)
Oklahoma - Oklahoma State
Oregon - Oregon State
Ohio State - Penn State
Michigan - Michigan State
All of those games have tradition, a history of good games, thrilling upsets, and not infrequently end up affecting the national championship picture.
When was the last time Pitt was in the top 5? It's been decades, surely.
WVU was last in the top 5 during the 06 & 07 seasons (going off memory).
Every single one of the rivalries I mentioned has had top 5 teams in it at some point over the last 5 years and definitely in the last 10.
