Less than 20 percent of FBS head coaches support a rule that would slow down games, according to an ESPN survey.
Of the 128 FBS coaches surveyed, 25 supported the idea and only 11 of those were coaches in the five "power" conferences (ACC, Big Ten, Big 12, Pac-12, SEC and Notre Dame).
Overall, 93 coaches were opposed to a rule change, nine coaches (seven percent) were undecided and one coach did not participate in the survey.
The new rule proposal would ban teams from hiking the ball until at least 10 seconds is run off the 40-second play clock, allowing defenses time to substitute. If an offense snaps the ball before the play clock hits 30, the team would be penalized five yards for delay of game.
An exception would be in the final two minutes of each half or if the play clock began at 25 seconds.
