The bettors flock to Oregon after the initial streak of athletes favored USC by nearly two touchdowns.

An outside opening streak at USC-Oregon State drove a deluge of bets on the underdog Beavers this week and left one sportsbook with more money on the line in the Pac-12 than any of the week’s NFL games.

Caesars Sportsbook opened Sunday USC as the 13.5-point favorite over Oregon. Minutes later, odds makers at Circa Sports put the Trojans as a 5-point favorite only. The discrepancy bookies swooped in, causing the streak to drop dramatically in Caesars and lift slightly on other bets, before settling on the consensus number of USC-6 on Sunday night.

“We had a great opinion of [USC],” said Joey Wiesel, leading college football dealer at Caesars Sportsbook. So we set a number to attract Oregon money. It has succeeded.”

The action of beavers-impacting bookies came straight away at Caesars, and Feazel moved the line down aggressively. Line archive from odds provider Don Best Sports show Caesars went from USC -13.5 to -9 within 30 minutes and dropped to -7 less than two hours after the opening number was published.

On Thursday, Caesars reported that 88.2% of the money wagered on USC-Oregon State point teams was on underdog Beavers, including a $110,000 bet on Oregon +7 placed Tuesday in Nevada.

Meanwhile, sportsbooks that opened USC as less than a landing favorite were reporting lopsided action on the Trojans. At DraftKings, 79% of the money bet on the spread of the game was on USC, and at SuperBook in Westgate Las Vegas, there were seven bets on Trojans each on the Beavers.

“I’m sure we’re going to need huge Beavers to start with,” said John Murray, CEO of SuperBook. “The Trojans are dear to the public once again.”

In the middle of the week, more money was bet on the USC-Oregon State spread than any other game in the third week of the NFL. Typically, handling betting on an NFL game would dwarf the bet amount on a college football game the size of Oregon-Oregon State, with both teams undefeated and the Trojans ranked seventh.

Feazel said he bounced back potential opening lines from his teammates on Sunday and reached agreement that USC should be a double-digit favourite. He said he didn’t think it would change much if given the chance to pull back but acknowledged the risk of the opening numbers moving big.

Some professional bettors will regularly play both sides of the matches to lower the stakes and hope for a winning margin of landing where they win both bets. For example, a bettor can take Oregon +13.5 in Caesars and USC -5 in Circa. If the Trojan wins more than six but less than 14, the bettor will win both bets. When the discrepancy in the point margins offered by sportsbooks is large enough, the difference does not matter. Smart bettors will bet on different numbers, especially if they include the more popular margins of victory, such as three and seven.

“You definitely don’t want to lose both ways,” Wiesel said. “You strive to get to the right number, but at some point you just have to take that risk and understand that there can be a middleman.”
