Paul Finebaum says the fun, so to speak, will come to an end for Colorado this weekend in Eugene.

The 19th-ranked Buffaloes take their unbeaten record on the road Saturday for what will be Deion Sanders’ first Pac-12 league game as the program’s head coach. Considering Oregon’s dominance at home in recent seasons and the Ducks’ own hot start to the 2023 campaign, there may not have been a tougher spot for Colorado to find itself in at the start of Pac-12 play.

And Finebaum predicts the Buffs will take their first loss of the season.

“I can only come up with one,” Finebaum said Tuesday on ESPN’s First Take when asked how many wins the Buffs the Buffs would get in their next three games.

After Oregon, Colorado faces USC and Arizona State.

He called Colorado’s first three opponents “run-of-the-mill, pedestrian teams.” The Buffs have wins over TCU, Nebraska, and Colorado State. The Horned Frogs started the year ranked, but that proved quickly to just be a reflexive spot given their CFP run a season ago.

“The competition is really getting ratcheted up,” he said. “We’re talking about some of the best teams in the country right now in Oregon and USC.

“Especially this weekend on the road, I just don’t think it’s possible that Colorado — with all the magic around this program that the two of you guys have helped create — is going to be able to get it done.”

Oregon is favored by 21 points at home on Saturday.

The Buffs will enter the game without standout receiver/defensive back Travis Hunter, who is set to miss at least the next two weeks after suffering a lacerated liver in the Colorado State game.

Quarterback Shedeur Sanders has lit the country on fire — he’s second in the FBS in passing yards, with 1,251 yards on a 78.7% completion rate — but Colorado has been very one-dimensional on offense. The Buffs rank 129th nationally in rushing yards per carry (1.99).

And defensively, they’ve played in shootouts twice, giving up 42 to TCU in Week 1 and then 35 to Colorado State last weekend.

“As much as I think we’d all like to see this train continue, it ends Saturday afternoon,” Finebaum said.
