EFL Manager Bookings

So the EFL have decided this season will see the trail of managers being able to recieve yellow and red cards, rather than just being sent to the stands.

Yellows will be shown for bottle kicking, undermining the ref and sarcasm! Every fourth yellow card a manager recieves over the season will see them gain an extended ban and possibly fine.

Reds will be for violent conduct, spitting and interfering with play.

Thoughts?

What's wrong with the current system? Managers get sent to the stands all the time.

This is meant to help with clarification for the crowd etc when the manager has had a talking to from the ref. Or so they say.
