It’s quite rare in RL to get beaten if you have out scored the opposition in tries.
Only a handful of tight games in RL have more than 7 tries where a kicking average of only 60% to win you the game even if the opposition has a 100% strike rate.
Only a try less games is where the game gets decided on kicks, and those games are extremely rare.
That is why I say, a good kicker doesn’t win you games, but he could lose you one.
It isn’t about the kicker, it’s about not having the try advantage, or having to rely on the opponent poor discipline to give the kicker a chance to make the difference.
