Why are the Hawkeyes favored against Iowa State?

SportsLine CFB analyst Tom Fornelli offered a blunt assessment of Iowa State's prospects.

“Iowa State could prove to be the worst Power Four team in the country, and I don't believe the market has caught on to how bad this team might be just yet. Yes, this game can get ugly at times, but I believe the Hawkeyes are the superior side this season,” Fornelli said.

For Iowa fans, this is a promising sign. The Hawkeyes have a strong defensive tradition, and the prediction market suggests they are expected to dominate the Cyclones. This is a key game for state pride and could have implications for the Big 12 and Big Ten standings.

What do analysts say about Ohio State vs. Texas?

In the marquee matchup, Ohio State travels to Texas. The Buckeyes are trading at $0.495 to keep the game within one point or win outright, while Texas is at $0.505 to win by two or more. SportsLine's Tom Fornelli explained his confidence in Ohio State:

“I believe both these teams are two of the best we have, but it's hard for me to trust the Longhorns in a spot like this because they continue to come up short in spots like this. I simply trust the Buckeyes more, and if I can get points with them, I'll take 'em,” Fornelli said.

This game is a rematch of last year's classic, and the prediction market reflects a near-even split, making it a compelling trade for fans.

How does USC's defense factor into the Louisiana matchup?

USC is heavily favored against Louisiana, with the Trojans trading at $0.475 to win by 32 points or more. SportsLine analyst Mike Tierney highlighted the Trojans' revamped defense under new coordinator Gary Patterson:

“We are buyers on the revamped USC defense, operated by new coordinator, Hall of Famer Gary Patterson. It has yielded just one rushing touchdown in two games. The defense even pulled off a pair of safeties in blanking Fresno State. For Louisiana, the scheduling leap from an FCS foe (Lamar) to a national title contender is beyond ambitious. As if the Trojans needed another edge, kickoff is 10 p.m. CT, an absurd late show for the Cajuns,” Tierney said.

This market offers a high-risk, high-reward trade for those who believe USC can cover a massive spread.
