What has changed for these two programs since last season?
Both sidelines look very different from the programs that closed out 2025. Utah swapped a two-decade head coach and its offensive play-caller in a single offseason, while Idaho already owns a game on the books and a fresh set of numbers. Here's what matters most for you and your outlook ahead of tonight.
Utah Utes
- New head coach. Morgan Scalley takes over from Kyle Whittingham, who left for Michigan after 20 years in charge.
- New play-caller. Kevin McGiven arrives from Utah State, so Devon Dampier works with an unfamiliar offensive coordinator for the first time in his college career.
- Dampier stays put. The dual-threat quarterback returns after 2,490 passing yards, 24 touchdowns, five interceptions and 835 rushing yards.
- Backfield continuity. Wayshawn Parker comes back after 981 rushing yards on 149 carries.
- Run-first identity. Utah went 11-2, finished third in the Big 12, and racked up 3,462 rushing yards, fourth-most in FBS.
Idaho Vandals
- Already tested. The Vandals played Week 0, losing 38-34 to Cal Poly on a touchdown with nine seconds left.
- A live arm. Quarterback Joshua Wood threw for 363 yards and two scores in that opener.
- A breakout target. Receiver Tyler Harste hauled in nine catches for 180 yards and two touchdowns.
- A brutal draw. Idaho arrives off a 4-8 season and travels to a stadium where Utah owns 17 straight home-opener wins.
What should I use Underdog for Utah vs. Idaho in CFB Week 1?
Underdog posts Higher or Lower projections rather than team lines. Utah enters as a lopsided home favorite, and the Utes have beaten their last four FCS opponents by a combined 216-23. The result itself ranks as the least interesting part of Thursday night.
As such, finding some wagers for this matchup could be tough looking at the game lines, but don’t worry; Underdog’s player projection CFB markets fix exactly that problem.
- Blowout-proof by design.
A 45-14 final ruins a game for anyone watching the scoreboard alone. Underdog asks a different question: does Dampier clear his rushing projection, does Harste clear his receiving yards? Both answers stay live deep into a one-sided night.
- You pick the players, not the winner.
Every selection reduces to Higher or Lower on one athlete's projected stat total. That format rewards research into snap counts, target share, and matchups rather than guesswork on a scoreline nobody doubts.
- Small entries, real engagement.
Underdog builds entries from as few as two selections, so your $5 qualifying play covers a Dampier pick and a Harste pick. Two players, one screen, ninety minutes of investment in a game you otherwise ignore by halftime.
- One board, every sport.
Underdog posts college football projections beside NFL, NBA and MLB, so your Underdog bonus code credit stretches right through fall.
- Geography matters.
Utah counts as a live state, so fans in Salt Lake City qualify on the spot. Idaho sits outside Underdog's footprint entirely, meaning Vandals supporters in Moscow miss out.
