Free Kick

Did any one see that today in the Giants and Cardinals game today?  I have been watching football for years now and never knew this rule existed.  The offense can try a kick at a field goal with a holder.  The defense can return it like a kickoff if it's no good.  The last time it was tried was 1968 by the Bears.  Judging by the results today it will be another 40 years before it's tried again.  I hope the Saints show up Monday night.  By the way I don't know if the Bears made it or not.
