Nebraska defensive line coach Rick Kaczenski wanted to see video of Saturday night's game before he thoroughly critiqued his players in front of a gaggle of reporters.

"If they didn't play well, that's my gig -- that ain't on them," the second-year Husker assistant said.

He looked tired. Sounded tired. Indeed, it was a long night for the defense. And Kaczenski has a challenging task this season, what with two true freshmen, three redshirt freshmen, a sophomore and a juco transfer playing significant minutes on the NU D-line.

"We'll get back to work," Kaczenski said. "Not only do they (Husker linemen) have to look at the tape, I have to look at the tape. I have to look at my routine, and they have to look at their routine, and see what we can do to help understand the game better and prepare better."

Kaczenski spoke in a manner that made it sound as if Nebraska lost the game, even though it held on to defeat Wyoming 37-34.

The Cowboys, however, accumulated 35 first downs and 602 yards. Nobody saw that level of production coming.

Kaczenski said senior defensive tackle Thad Randle, who has a long history of knee problems, held up "pretty good."  He had three tackles.

Redshirt freshman Vincent Valentine (four tackles), who started alongside Randle, did "all right," the coach said.

"They did some things blocking-wise that made those 'A' gaps a little big for him," Kaczenski said. "We have to do a better job of throwing off blocks. But that's me. That's not Vincent."

Valentine, in his first college game, was "probably a little bit wide-eyed, a little bit anxious, a little bit nervous. That's the type of kid he is. Things are important to him. He probably burned a lot of energy prior to the game.

"I think he's a guy who will continue to get better each week."

Same goes for the rest of Nebraska's young linemen -- that's the hope at least -- including touted juco Randy Gregory (6-foot-6, 255 pounds), who had two tackles and was robbed of a sack when he was called for roughing the passer.

"We have to get him to relax a little more and play," Kaczenski said. "He was probably over-thinking some things. But he's a guy who gives us a little bit of juice."

The Huskers recorded no sacks. They did, however, get decent pressure on Brett Smith. Of course, Smith is extremely mobile. He's adept at dodging pressure and throwing on the run, or off his back foot, or from other awkward positions.

The key against that type of QB, Kaczenski said, is disrupting his rhythm. Getting in his face.

"He can't have a clear vision of his target," the coach said. "Those are things we have to clean up -- get into those windows."

Give the junior quarterback credit. Give the Wyoming offense credit.

"He's a dang good quarterback," Kaczenski said. "He's one of the things that made us nervous going into it, his presence in the pocket, his scramble ability. Not only his scramble ability, but his ability to keep moving and extend the play with his eyes down the field.

"A lot of young quarterbacks, they just take off and run. This guy (Smith) does a great job of getting the ball to his open receivers. We have to learn from it, and we have to learn from it fast ... We have to make a huge jump this week."
