Big 12 internal affairs: Could QB change be brewing at Colorado?

Posted by ESPN.com's Tim Griffin

Here are a few tidbits from around the Big 12 this week as teams prepare for their games on Saturday:

COLORADO: The patchwork starting offensive line in front of Cody Hawkins is giving Colorado coaches more impetus to consider allowing backup quarterback Matt Ballenger to get more meaningful minutes. Despite Ballenger getting some playing time late in the Texas game, don't look for Colorado coach Dan Hawkins to bench his son -- yet.

TEXAS: Longhorn coaches have demanded that team photographers take pictures of ball carriers throughout practice and games this season to help develop better ball-handling techniques. Pictures of players with bad technique are prominently displayed in the Longhorns' meeting room. "We tell them that the eye in the sky doesn't lie," Texas coach Mack Brown said. The attention apparently has helped as the Longhorns have lost only three fumbles so far this season, including none by a running back.

TEXAS TECH: Tech cornerback Brent Nickerson will again start this week in front of L.A. Reed, although the two players have seen about equal action in the last two games. Tech coaches believe Nickerson will be better prepared to start against Nebraska because he's played against a similar offense to the Cornhuskers earlier this season.

NEBRASKA: Nebraska coach Bo Pelini acknowledges he made a big mistake in the scheme he cooked up to try to halt Missouri last week. The Cornhuskers employed a three-man front with a fourth lineman shifting before the snap who tried to blitz through one of the wide gaps on Missouri's offensive front. Chase Daniel wasn't fazed and Derrick Washington gashed them for 139 rushing yards -- third-most ever by a Missouri running back against Nebraska.

MISSOURI: The Tigers cooked up some additional defensive pressure against Nebraska with some new looks that got a better push up the middle. The Tigers had seen a lot of seven-man and eight-man fronts that made pressure difficult to generate defensively. More defensive pressure will be vitally important in the next two games for the Tigers against Oklahoma State's Zac Robinson and Texas' Colt McCoy, who both rank among the top four nationally in passing efficiency.
