I am usually against all the persistent rule tamperings but on the back of the Hudson "what?" 50m and the numerous other harsh and ridiculous 50 metre penalties would it be worth introducing the 25m penalty?
The 25m works quite well in the SANFL and it would give umpires somewhere to go when it is one of those "two steps over the mark" kinda 50's etc. At the same time it could be another grey area and they might start paying more (not being so put off as it is not such a huge penalty). From memory the 15m was taken away because teams started giving them away purposely to slow down the other team and with the zone setup this could also reoccur.
Ultimately I would rather a little more common sense to prevail (like it seems to on grand final day) but it looks like these often game changing penaties are here to stay. Would it be worth trialling it in a preseason instead of the other nutbag stuff they trial?
