Five starting QBs—15.6 percent of the league’s total—will have been coached by just two men: Mike Leach, the scatterbrained genius who brought the Air Raid and an obsession with pirates to the college football mainstream, and Kliff Kingsbury, who played quarterback for Leach at Texas Tech and later became the head coach of the Red Raiders. (The QB count rises to six if we count Kyler Murray, considering that Kingsbury is now the head coach of the Arizona Cardinals.)
