Kind of on topic - IMO, one of the worst rule changes was to stop requiring players to sign their cards.
I am speaking of paper scorecards - taking away that requirement relieves the the onus of each player being accountable that their score was correct....which in turn removed the one absolute a TD had when approached about incorrect scoring.
A players signature = no excuses, reasons, circumstances....nothing.
No signatures required, opens back up a never ending list of excuses, reasons and circumstances that can be argued/presented by the players.
Makes no sense.
Who's to say a person won't alter the card after everyone initials it?
