This just makes far too much sense to ever be brought to reality.
I thought so as well, and I am loathed to admit Clarkson ever has a good idea. Still though, it would almost eliminate congestion as teams would want get it out of congestion as soon as possible, and if they can't then a free kick is going to be awarded pretty quickly, thus opening up the play again. Situations where you get stoppage after stoppage would be a thing of the past.
