I agree Salsa.
Karma has struck one more time.
As to the refs having to run more, so what? They are well compensated and if they cannot do the job, get them off the field, with a hose, if need be.
I can see this as plus overall to the game, it should allow for better calls on both sides of the ball, not really favoring one side or the other.
The funny thing will be that we would see on TV how defensive linemen would go crying to the either the ref or the sideline judge and cry about holding and tugging and all that song and dance. NOW, the rolls will be reverse and the defensive linemen will be the ones with the evil smile.
Maybe that is their problem. They eat too many rolls.
