But if, as a defender, you knew you would give away 7 points if you infringed, you would think twice about giving away a penalty - thus allowing the attacking side that bit more time to ensure quick ball and therefore create a try-scoring opportunity.
In the Argentina match, for example, would so many penalities have been conceded by Argentina had the points for a penalty been higher than the current 3?
I'm happy to acknowledge 7 points might be too high but I'm of the view that the current 3 points is not enough.
Another alternative might be to have a 'Penalty Spot' in front of goal 15 metres out. Any penalty conceded inside the 22, regardless of whereabouts inside the 22 the infringement occurred, means the penalty is taken from the spot (and is therefore an almost guaranteed score).
