Pulley had been competing with sophomore Mike Hartline to succeed Andre Woodson as the Wildcats' starting quarterback. Hartline will begin preseason camp as the starter.

The former Atlanta Falcons coach said he had great expectations for a team that lost a two-time Heisman Trophy runner-up and other skill players from an 8-5 team coached by Houston Nutt, now the coach at Ole Miss.
