Require turf?   
 
I posted this elsewhere but seems to fit here....  Onside Kick Was Dirty Pool     
The author's premise is that onside kicks at the start of a half are unfair, because each team should "receive" the ball when it is their turn.  With the outlandish points Mpls makes on this board, he may very well be the author.  There is a poll on the site in which 2.5% of the readers agree with him.  96.7% disagree, many leaving humorous comments.
