Snowball The answer should be to say "In order to award a penalty you must feel CERTAIN it was a penalty.
Same with handball
If in doubt, don't award
I would rather it was harder to win a penalty
and there were less of them
Do you think referees currently are just guessing? They give fouls because they think they're fouls.
Frankly not enough penalties are awarded at present. Defenders get away with far too much cheating. I can see the case for making the penalty area smaller, which would both stop goalkeepers having such a disproportionate influence and stop penalties being awarded for fouls that are really quite far from goal, but the rules shouldn't favour defenders cheating. Football has come a long way in recent years to stamp out the ugly brutality we used to see, but there's still work to be done.
