Linebacker Sam Eguavoen said Smith is quieter and there is less screaming. He said that when Smith says something he has the attention of the defense because he does say less.
"He comes at you more like a man than a child," Eguavoen said.
"He has a lot of enthusiasm and he is really good with the players and we've had some good practices on that side of the ball," Kingsbury added.
The defense has had its problems and were under siege against Arkansas, allowing 438 rushing yards and 499 yards of total offense. The feeling of watching the tape was the kind you get when you are sick to your stomach.
While the defense has struggled, Kingsbury isn't heaping praise on the offense and says they need to score more and protect the football. The blocking has not been a problem as the offensive line has not allowed a sack in three games. Of course, the Tech defense only has three sacks.
"We feel pretty good about it and it is a source of pride," center Jared Kaster said. "We were supposed to be the weakest part of the offense and we are one of the strongest. Our job is to make Davis Webb a better quarterback. He's helped out and done a good job avoiding the sacks, but we've done a good job of protecting."
This may be one of the most fun matchups to watch as the Cowboys defensive line is sack hungry. They could do a number and force Webb into mistakes as he has already struggled some this season.
"I remember being a sophomore and I remember being booed off the field here," Kingsbury said. "I remember Graham Harrell being booed off the field. Davis is going to be fine. He knows what he is doing and he is maturing. He is going to be fine."
Of course, the last time Texas Tech won in Stillwater was 2001 when Kingsbury was the quarterback. The Cowboys have won five in a row over the Red Raiders and getting six in a row looks easier now than it may have in August. Getting sacks may be harder, but that may be about it.
