Nebraska was pretty quick, I remember when the Big Ten initially announced their plans for expansion it was underwhelming additions like Mizzou that were getting batted around. Then like a week later the Columbus radio guys had Tom Osborne on, and he was lobbying hard for Nebraska, which was just an unrealistic pipe dream that was quickly dismissed up until that point. Then Pete Fiutek came on next, and they told him what Osborne said after hearing his own inane speculation, and it was the first time he'd ever heard of it. Then it just snowballed from there.
