FILE - In this Aug. 31, 2013, file photo, Temple coach Mark Rhule yells to his team during an NCAA college football game against Notre Dame in South Bend, Ind. Rhule shares some of the safety concerns held by Arkansas' Bret Bielema and Alabama's Nick Saban about how hurry-up offenses increase the number of plays per game and don't allow defenses to substitute for fatigued players. Rhule said it's better to be out in front of a potentially dangerous situation than too late. (AP Photo/Michael Conroy, File)
