It comes down to winning games. If Nebraska wins games, then there is no reason they can't recruit with the likes of Michigan, Ohio St., and the "daunting" SEC schools as well..... The OP was thoughtful, and well put, but it is a very narrow minded opinion, that doesn't look too far into the past, or too far into the future.... The OP seemed to have the assumption that Nebraska, and the B1G should accept the SEC for what it CURRENTLY is. I don't know if many of us can speak for the other B1G schools, but I promise you that as Nebraska fans, we EXPECT our team to get back to the level where we smack around the best programs. Yes, even the USC's, Florida's, and Alabama's of the world.
There is no reason Nebraska can't return to greatness, our school's location is not something new in the last decade. Winning takes care of everything. If we win, we get the best players, and become the best team.
The SEC can be beat (proof below):
62-24
