Here's a play I'm playing tonight that follows the unranked-ranked general logic (but doesn't fall under the system).

UNLV -1.5 vs Texas Tech
UNLV hasn't been good in years. They have lost 5 games in a row and are 2-5 on the year. Meanwhile Bob Knight's Texas Tech is a public team that went to the Sweet Sixteen last year. They are not off to a great start but they have a winning record and they played Wake Forest pretty close. Surely they're not going to lose tonight on national TV to crappy UNLV team right? How the hell is UNLV favored here? 2/3 of all bettors think the linesmakers have got it wrong and are betting on Tech. My money's going the other way.
