AMES, Iowa (AP) - Iowa State needs to pump some juice into its offense, and the Cyclones need to do it quickly.

That doesn't mean coach Paul Rhoads is about to change quarterbacks, but it's a fact of life in the freewheeling Big 12 Conference that a team can't survive without a productive offense.

Iowa State stalled repeatedly in a 24-13 loss to Texas Tech last Saturday. Quarterback Steele Jantz passed for only 73 yards while committing four turnovers, reverting to the form that got him benched last year.

Rhoads says Jantz wasn't the only problem with the offense. He says he'll watch Jantz and backup Jared Barnett closely in practice before deciding on a starter for Saturday's game at No. 15 TCU.
