The juice went up on that though. So just because it says Nebraska is favored, your return on betting on M1chigan is worse. And the money line moved just five points, so not really a big change. Or in other words, a $100 bet nets an additional $5.
I actually think this is a way to attract bets on Nebraska because they want people following “sharps” when they really aren’t shifting the value of the bet one way or another. A Nebraska favored 1.5 with a M1chigan now down to -120 means it’s more appealing to bet Nebraska then it was before the line flip.
BTW, I’m not seeing that outside of ESPN. FanDuel, DraftKings… the list on Vegas Insider is still showing everything as a UM favorite.
