On the first play of his college career, Colorado outside linebacker Jacob Callier raced past the right tackle and found himself in the Colorado State backfield.
Callier then performed a spin move to get away from the running back trying to block him. Unfortunately, in mid-spin, Callier had his back to the quarterback he was trying to reach and missed the opportunity for his first sack.
"I should have got a sack, I felt bad about it after, but most definitely a learning experience for me," he said. "Next game, I'm not going to miss it."
While he missed the sack, that play and that game signaled Callier's arrival.
An impressive fall camp has put Callier, an 18-year-old true freshman, in position to make a big impact this season. That first play came on the third snap of the game, and Callier was on the field a lot as a pass-rush specialist against the Rams.
"It's pretty much: Get the guy with the ball and get after it," he said. "If I can affect the dude throwing the ball, I'm doing my job."
Callier got his first sack later in the game and was also credited with a quarterback hurry.
The fifth Callier brother to play college football, Jacob didn't expect a slow start to his career. He starred at St. John Bosco High School in California, one of the top prep programs in the country, and was confident all along that he could compete immediately at CU.
"My plan coming in, that was my mindset: I'm going to help this team no matter what," he said. "Being able to actually have that come true is a big step up for me. I'm willing to help my brothers go far.
"It's a dream come true, coming from a football family and being able to do this. It's making my pop smile a lot."
After the game against the Rams, Callier said the skill position players for the Rams were faster than he was used to in high school but going against the linemen was "not too bad."
Going forward, he's hoping a good debut is just the start for a great season.
"I got my first game jitters out, so next game hopefully I do a little bit better," he said.
Junior Josh Kaiser got his first career start on Friday, playing at left tackle in place of suspended senior Jeromy Irwin. It was the latest step in what has been a great offseason for Kaiser.
"I trust Josh," CU offensive line coach Klayton Adams said. "Josh had a few (bad) moments just like the rest of them did, but Josh also had some really good moments and had some plays where we he was able to play physical. His length helps him at tackle."
Like the rest of the line, however, Adams said Kaiser has to improve.
"He's going to need to play better than he did Friday in order to be a guy that breaks into the (starting) group, but he's one of the guys I've been happy with the whole year, the amount of improvement that he's made," Adams said.
It remains to be seen if Kaiser will get another start on Saturday against Texas State. Irwin was one of four Buffs suspended for the game, along with tight end/defensive end George Frazier, defensive lineman Frank Umu and cornerback Anthony Julmisse (who has been suspended since July).
Asked Monday if the Buffs will get any of their suspended players back this week, head coach Mike MacIntyre said," I do not know the answer to that yet."
MacIntyre was in the middle of breaking down film Sunday night when one of his assistants told him to turn on the UCLA vs. Texas A&M game.
MacIntyre caught the last four minutes of UCLA's miraculous comeback, where the Bruins rallied from a 44-10 deficit to win 45-44.
As UCLA was rallying, MacIntyre said he and the coaches starting going over how to handle late-game situations.
"We took out our time sheet on how to manage a game at the end of the game," he said. "We went through it and talked through it ... and then watched it unfold.
"That was an amazing finish. I'm happy for (coach) Jim Mora and the UCLA Bruins and the Pac-12. That was pretty cool."
MacIntyre gave the players time off Saturday and Sunday because it was the last chance to have two consecutive days off until after the Buffs play USC on Nov. 11. ... MacIntyre said in watching film of Texas State, he's impressed with Bobcats quarterback Damian Williams, as well as their linebackers.
