Bet volume has been trending Washington while total dollars is trending Oregon. It’s the public picking Washington and sharps picking Oregon. Both have been known to be wrong in big ways, just providing the data trend. It’s about a 63-37 split in bet volume favoring Washington and the points.
It's my understanding there would be no math on this bored.
But I also thought that the sharps tend to come in the day before a game once the line has settled and they see an arbitrage opportunity (I concede that I am certainly not a "sharp").
Sharps do a lot of things. It was large sum bets that originally drove the spread from -7.5 to -9.5. Large bets are assumed as sharps even though there are a lot of rich idiots who just get the itch and don’t have much knowledge. But general the larger the bet, the more likely it’s a sharp. They make big bets when they see an advantage. What I think will happen is they already got the Ducks at -7.5. I have a feeling they are hoping this gets bet to -10.5, then they go hard on Washington. That creates the arbitrage that if Oregon wins by between 8-10 points, the bettor wins on both tickets.
