AMES, Iowa (AP) - Iowa State could not have picked a better time to host the nation's worst defense.
Quarterbacks Steele Jantz and Jared Barnett have both earned and lost the starting job in the past three months. Coach Paul Rhoads won't let anyone know the starter until Saturday night's game against Baylor.
The Bears (3-3, 0-3 Big 12) have given up 70, 49 and 56 points in the past three weeks, all losses.
Baylor's porous defense will meet up with Iowa State (4-3, 1-3) and its stagnant offense Saturday night - a matchup between teams with major issues and little time to get them fixed.
