The NCAA football rules committee is proposing some changes for the upcoming season, one of which is designed to ease defensive substitutions. The proposed rule would allow defenses to substitute within the first 10 seconds of the 40-second play clock, except in the final two minutes of each half. Any offense that snaps the ball before there are 29 seconds left on the play clock would incur a 5-yard delay-of-game penalty. Naturally, this would slow down some of the up-tempo offenses that have taken over the college game.

Many coaches, particularly those of fast-paced offenses have already begun expressing their displeasure with the new rule. Oklahoma State head coach Mike Gundy for one, took to Twitter to rail against the proposed change, likening it to taking away the shot clock in basketball. Gundy joins coaches like Arizona's Rich Rodriguez and Mississippi's Hugh Freeze on the record against the new rule.
