That's likely to change on Saturday when the Buffaloes (2-1) visit Oregon (2-1) in the Pac-12 opener.
The Ducks have gone for two on 11 of their 18 touchdowns this season, with just four of those conversions being successful. Last week in a 35-32 loss at Nebraska, the Ducks went for two on all five touchdowns, failing on four.
Receiver Charles Nelson has been Oregon's two-point specialist. Six of the 11 attempts have come on his runs and on two others, he threw the ball.
While the Ducks haven't been overly successful on their two-point conversations, they've forced teams like Colorado to be prepared.
"That's one of the reasons Oregon does that, so you'll spend time working on that," CU head coach Mike MacIntyre said. "You have to spend time in practice every day working on that, which takes away from working on things from their offense."
CU has not had an opponent attempt a two-conversion since Hawaii did so in the 2015 opener, on the first touchdown of the season.
One of the keys to CU's success this season has been the Buffs' focus on doing their job, rather than worrying about the opponent. Receiver Jay MacIntyre said that hasn't changed this week.
"We feel like we can win every game we play," he said. "It's not really about Oregon. It's about us. That's how we go into every game.
- Colorado and Oregon are the only teams in the Pac-12 that have not thrown an interception this season. They are two of only 10 teams in the country without an interception. Of those 10, CU and North Carolina are tied for the most attempts (98).
- CU is tied with North Carolina in another category. The Buffs and Tar Heels have forced at least one turnover in 16 consecutive games - the longest streak in the country. For CU, that represents every game since Jim Leavitt took over as defensive coordinator.
- Oregon has been the most penalized team in the Pac-12 this season, averaging 11 penalties and 104.7 penalty yards per game. CU has had the second-fewest penalty yards, at 39.3 per game (5.3 penalties).
- CU junior receiver Devin Ross ranks fourth in the Pac-12 with 6.0 catches per game. He is seventh in receiving yards per game (67.3). Teammate Shay Fields is third in yards per game (85.3).
- In 20 previous meetings with the Ducks, the Buffs have never had a 300-yard passer. The best total was 282 yards by Steve Vogel on Sept. 15, 1984.
- Oregon running back Tony Brooks-James has scored a touchdown in four consecutive games.
