The NCAA Rules Committee.
A bunch of fucking retards if they pass this.
The defense is bitching because they can't substitute. Here's the problem: THE OFFENSE ISN'T SUBSTITUTING EITHER!
It's not like the offense is getting to run fresh legs onto the field. They're tired too. If they aren't tired? They're just in better shape.
This is 100% old grey hair geezers who need to die off. They want to see their traditional football played by big fat asses running the power I with the occasional implementation of that crazy idea they concocted a few years back known as the forward pass. They don't want to see those slick looking kids with shiny uniforms running down the field like it's a basketball game.
There's no evidence that the HUNH causes more injuries. If anything, I'd hypothesize that the power type of football that LSU and Alabama plays causes more injuries.
The only issue anyone can have with the HUNH is that traditional defenses can't stop it. What's the fucking point of a play clock if they pass this rule? Just let the refs determine when it's proper to snap the ball. They'll blow the whistle then say, "Down, set, hut." That's the best way to make it completely fair.
