Gundy voices opposition to rule change

The NCAA football rules committee is proposing changes for the 2014 season that would loosen the reins on defensive substitutions. The committee's proposal would allow defensive players to substitute within the first 10 seconds of the 40-second play clock, except for the final two minutes of each half.

Several coaches have come out against the proposal, including Oklahoma State's Mike Gundy, who took to Twitter on Thursday evening to voice his opposition.
