FRISCO, Texas -- Kellen Moore isn’t sure where the playbooks are now. Maybe a few are still at his parents’ house, tucked away somewhere in a room or attic.
Some people collected baseball cards or video games. Growing up, Moore would search the internet looking for different playbooks.
He had NFL offenses, like the West Coast and the number system the Dallas Cowboys used in their Super Bowl run of the 1990s and continue to use today. He had the college offenses, like the run 'n' shoot and the Air Raid, favored by Mike Leach.
