Ankle surgery forced Crouch to redshirt for the 1997 co-national championship-winning season. In 1998, Bobby Newcombe began the season as the starting quarterback, but he was sidelined by a knee injury after the first game and Crouch took over the starting duties. Against UAB, Crouch rushed for two touchdowns and completed 11 of 17 passes in his first career start. 1998 proved to be a chaotic season for the Cornhuskers. Crouch made another start before being replaced by a healthy Bobby Newcombe. Newcombe started the next five games, but was pulled in the middle of a game because of a PCL strain. Senior walk-on, Monte Christo, took over for Newcombe, and started the following week against Texas. With Texas leading 10-0 in the middle of the second quarter, Christo was pulled and replaced by Crouch. Crouch remained the starter for the rest of the season, which ended with a 23-20 loss to Arizona in the Holiday Bowl.
