All 25 ranked teams are in action in Week 3 of the college football season, although only two matchups pit ranked teams against each other.

Five interesting trends sportsbooks are reporting:

5. Post-Frost Era Begins

Nebraska fired coach Scott Frost following a 1-2 start to the season. But that hasn't deterred bettors from wagering on the Cornhuskers' home game against No. 6 Oklahoma on Saturday.

The game has attracted the largest percent of bets and handle at both BetMGM and BetRivers for Week 3. That's despite a double-digit spread, with the Sooners favored by 13.5 points at BetRivers after opening as 11-point favorites.

Oklahoma has drawn 79 percent of the spread bets and 59 percent of the handle, while the Sooners' -500 moneyline has been backed by 91 and 90 percent of the action, respectively.

4. Utes Feeling the Love

The most lopsided spread action at PointsBet has been in favor of No. 14 Utah against visiting San Diego State. Despite the line holding steady at 21 points this week, the Utes have been backed by 89 percent of the bets and 94 percent of the handle.

The action has been more split at BetRivers, where Utah has drawn only 48 percent of the spread handle as 21.5-point favorites. However, the Utes' -2500 moneyline has been backed by 96 percent of the money.

3. Service Treatment

The second most popular play at BetRivers involves a pair of unranked teams on Friday night. Air Force covering its 16.5-point spread at Wyoming has drawn 66.62 percent of the handle, second most at the sportsbook only behind Notre Dame covering an 11-point spread against California.

The 15.5-point line at DraftKings has drawn more split action, with Air Force backed by 64 percent of the spread bets while Wyoming is being supported by 57 percent of the money.

2. Feeling Sparty

Bettors are jumping on Michigan State as a road underdog at Washington. The Spartans +3.5 points has been the second most wagered-on game at BetMGM, where Michigan State has been backed by the second most amount of total bets (80 percent) and money (81 percent) this weekend.

The story is similar at DraftKings, where the Spartans have drawn 79 and 66 percent of the action as a 3.0-point underdog.

1. Jimbo Renews 'Canes Rivalry

The "marquee" game of the weekend pits No. 13 Miami at No. 24 Texas A&M on Saturday night. The Aggies are expected to make a change at quarterback following last week's stunning upset loss to Appalachian State.

Texas A&M coach Jimbo Fisher used to face Miami annually while at Florida State, while this game serves as a big litmus test on the road for new coach Mario Cristobal's Hurricanes.

It has not been among the most heavily bet on games at BetMGM or BetRivers, but some interesting trends have emerged nonetheless.

Texas A&M is a 6.0-point favorite at BetMGM, with the line moving from 6.5 as Miami has been backed by 63 percent of the spread bets and 70 percent of the money. The line is also 6.0 points at BetRivers, with the Hurricanes drawing 55 percent of the spread bets but the Aggies backed by 56 percent of the money.
