Patton was a very good goal kicker in his U19 days, and we know from Ratchford's performance this year what a bit of practice and application can achieve. Price seems to be a 'thinking' coach, so you would presume that he has had Patton practicing all season for this sort of eventuality, in exactly the same fashion that he brought in Jake Mamo to cover wing and FB injuries.
But I guess we will soon find out whether that's true or not.
