Colorado Defense Faces Early Pressure Before A Much Tougher Test

As Northwestern looms, Colorado must confront their defensive vulnerabilities to stave off potential upset.

Colorado walked away from a 52-21 win over Weber State with plenty to like on the scoreboard and plenty to clean up on film. The Buffs put up 52 points and led 42-14 at halftime, but the defense still surrendered 372 yards to an FCS opponent - the kind of number that won’t sit quietly with a unit that knows what’s coming next.

The challenge changes fast. Northwestern brings in a quarterback with 21 career college starts, and Aidan Chiles already showed what that can look like in the Wildcats’ 34-18 win over South Dakota State on Sept.

  1. Chiles finished 14 of 24 for 273 yards and a touchdown, added a 14-yard rushing score, and opened his season by firing a 71-yard strike to Griffin Wilde, a third-team All-Big Ten receiver who caught 71 passes last season.

That attack is being run by Chip Kelly, now in his first season at Northwestern. Kelly called plays for a national title team at Ohio State, then spent last year as the Las Vegas Raiders’ offensive coordinator before being fired in November after a 2-9 start. Northwestern had last weekend off, giving Kelly two full weeks to get ready for Colorado.

After Weber State, the Buffs’ defenders kept coming back to the same issue: not effort, but execution.

“The effort was there for the entire game, I think even to the last second,” linebacker Tyler Martinez said. “And then just the communication.

We were on the same page the whole game. Little things tore us apart in some of those plays.”

Safety Randon Fontenette pointed in the same direction.

“It’s not the defensive scheme, because coach Marve is going to call a great game every time,” Fontenette said. “It’s really on us just owning up to doing our job and trusting each other. Just tighten up on the little things.”

A lot of the damage Saturday came after the game had already tilted heavily Colorado’s way, something Fontenette described without trying to dress it up.

“We’re human still,” he said. “We have emotions, we have egos.

When you get up like that, people pull their foot off the pedal. But coach Marve kept emphasizing we’ve got to keep going until the clock hits zero.”

Colorado does have some things holding up. The pass rush has been one of them.

Lamont Lester Jr. has a sack in each of the Buffs’ first two games - four total - and Colorado added 10 quarterback hurries and nine tackles for loss against Weber State. South Dakota State got to Chiles twice, and Northwestern knows what happens when the ball gets loose: Chiles threw 11 interceptions in 2024, and the Wildcats went 1-5 last season when they turned it over twice or more.

The run defense has been steadier. Colorado allowed 51 rushing yards at Georgia Tech and 127 against Weber State, and its defensive line earned Big 12 unit of the week honors after the opener. Northwestern, meanwhile, went 5-0 last season when it ran for at least 199 yards and 2-6 when it didn’t.

Martinez said the late-game snaps offered something useful, too.

“Some of those guys who came in late in the game played their butts off,” he said. “Knowing they can come in and provide support when we need them to, that’s a big deal for us on defense.”

Even with that, he wasn’t interested in pretending the unit is where it needs to be.

“We just need to learn and notice that we’re not as good as we want to be yet,” he said. “This isn’t the end goal.”

Fontenette didn’t sound like a player planning to wait long for the fix.

“It’ll be fixed vs Northwestern,” he said.

Kickoff is set for 5:30 p.m. MT on Saturday.

Colorado also learned Monday that its Sept. 26 trip to Baylor will be its first early kickoff of the season. The Big 12 announced the Buffs and Bears will play at 10 a.m. MT, with the game set for ESPN or ESPN2.

Colorado Depth Chart Battle Is Starting To Get Real Fast

Colorados home opener gave the Buffaloes plenty to sort through, and not all of it was about the final score. The offense spread production around in a way that highlighted just how much competition is already baked into this roster, with two receivers and a running back all topping 100 yards. Joseph Williams stood out in particular, piling up 123 yards and two touchdowns while Elliott Arnold calmly drilled a 52-yard field goal on his first college attempt.

Multiple quarterbacks also saw the field, and freshman Kaneal Sweetwyne even added a rushing touchdown in relief, a reminder that the depth chart is not going to settle itself anytime soon. The other side of that coin was hard to ignore, though, because Colorado also finished with 13 penalties for 107 yards, leaving coaches with a clear list of things to clean up even as the internal battles for snaps start to sharpen.

Colorados 2027 QB Plan Just Got More Complicated

Colorados quarterback outlook for the 2027 class got a little more crowded when Cameron Pooley of Mater Dei High School verbally committed after a recent trip to Boulder for a home game. The Buffaloes extended a scholarship offer through director of player personnel Darrien Darden-Box, and Pooleys decision gives the staff an early piece to build around as it maps out the position for that recruiting cycle.

Even with Pooley in the fold, the picture around 2027 is still far from settled. Colorados quarterback room for that class remains thin, and the staff is also weighing four-star recruit Andre Adams as part of its broader plan, which suggests the Buffaloes may not be done reshaping the position just yet.

Colorado's Fast Start Set Up A Much Bigger Test For Deion

Colorados 2-0 start has given Deion Sanders and his staff plenty to like, beginning with Julian Lewis first 300-yard game and a defense that has looked sharper under coordinator Chris Marve. The offense has also shown signs of settling in under coach Marion, with the changes helping key players like Micah Welch become more effective and giving the Buffaloes a more balanced look than they had at times last season.

Still, the early surge has done more to raise the stakes than answer every question. The defense has shown some vulnerability, and the schedule is about to bring a very different level of resistance, the kind that will show whether this fast start is a sign of real growth or just a strong opening act.
