I love to see this. And with a return to winning and possibly completing for championship, this ranking likely improves.
However, if there isnt a return to winning (and probably at a high level at some point), I can easily see where these numbers start slipping, and slipping rapidly, when those of us currently 40+ are the only ones who actually remember the glory years. At worst, that puts the program at Indiana/Northwestern level, and at best maybe where Minnesota is right now. We're not on this reality's doorstep, but without a return to winning, maybe 10-20 years from now?
I haven't lived in Nebraska for decades now, but even the alumni association in Phoenix has seen reduction in numbers. And for those of us that actually show for some of the association events, at 50, I'm one of the youths that makes up this group. And in general outings, I see fewer people wearing Husker gear out here and CA than I did a decade ago.
