I think it all depends on how you measure it.
Like you said, 0-8 in champ games. But that's only one measure.
I don't think the weakest East programs are anything special. And that's obvious, I don't think anyone would really disagree.
Mich St is a program like Wisconsin and Iowa. 75k attendance when they're good, and they have some sparks now and then.
It's really just the three elite programs with 100k+ stadiums, that set the East (and the Big Ten frankly) apart.
Nebraska is the closest that, on paper, the West has to that and they're only 80k stadium/attendance (would be interesting if they expanded to 100k in a fit of narcissism, if they'd still sell out the damn thing). Of course, they're come nowhere close to what they did in the 90's and early 2000's, and it's becoming clearer every year that they'll never get that back. Different era, different ability to bend/break rules, different rules altogether.
