That's probably mostly true and all, but a few things:
1 - Texas @ South Carolina will be a sellout, because even the SEC's ne'er-do-wells sell out. Maybe USCe showing up in Austin won't be a whole big thing, but that's on them.
Florida @ OU should be huge - the Sooners playing @ Auburn will be massive. Over and over and over again.
2 - aside from the jokes about B1G teams getting to play in the RB every few years now, won't USC @ Iowa feel like a RB matchup to them? Maybe not for all matchups, but I feel like Wisconsin @ UCLA will feel bigger than a normal away game....USC @ MSU will feel bigger than average. It's like a bunch of mini-RBs week after week.
