national championship contenders being upset late in season?

[gojetsgomoxies]

trying to figure if this is good angle or if it's just a few highly memorable results

i remember:

pitt over WV (was WV playing backup?... line was 28 or similar i think. thursday night?)

osu over okla (before OSU was really good)

vaguely remember another OSU over oregon. not sure if that's correct...

my thesis is ND may suffocate from the pressure??
