It is little more than a decade since Wales' full-back situation was last unsettled.
Think back to the start of the 2011 World Cup and the No. 15 jersey was something of a problem position.
James Hook was the man in possession, but his talents were best served elsewhere. Lee Byrne was in the squad as the most natural option, but he was firmly out of favour with the coaches.
And then there was Leigh Halfpenny, who wasn't even an option until he was thrown on midway through Wales' pool stage win over Samoa.
And then, suddenly, it was settled.

From then on, the jersey has largely belonged to either Halfpenny or his challenger Liam Williams, who emerged on the Test scene shortly afterwards.
As a result, Wales have been blessed in the position.
However, this autumn Wayne Pivac will likely have to start the autumn series in an unfamiliar position as a Wales coach: being without either Halfpenny or Williams.
Players on the fringes of the Wales team like Johnny McNicholl, Hallam Amos and Jonah Holmes have all been mentioned in dispatches as potential replacements, but potentially the best option could be someone already nailed on to start against New Zealand on October 30: Josh Adams.
Now, bear with me on this.
Adams has played 32 times for his country, scoring 17 tries.
With that record alone, you would have to question whether it is worth moving Adams away from the wing given how prolific he is there.
And, of course, if Adams plays full-back against New Zealand, that leaves you scratching around for two first-choice wingers to replace, given Louis Rees-Zammit will be on club duty in England and won't be released for the All Blacks clash outside the official Test window.
Those are fair points.
Owen Lane was likely to come in for Rees-Zammit, while one of McNicholl, Holmes or Amos could deputise on the other wing.
When Halfpenny shifted from out wide to covering the back-field, his spot as a starter had been taken by a fresh-faced George North, but there is definitely nobody threatening to usurp Adams from the XV just yet.
But, hypothetically, a shift to full-back could potentially open up more opportunities for Adams and Wayne Pivac.
Pivac has noticeably favoured having a balance in his back-three of a link player and a finisher.
Were you to partner Adams with McNicholl and Lane in a back-three, you'd have those two facets covered up easily.
But shifting Adams around to full-back could open up a few intricacies.
A lot of Adams' work for Wales is done through working across the pitch, while the other wing - often Rees-Zammit - tends to hold their width a little more.
However, were you to swap McNicholl and Adams, it would allow the Scarlets star to perform that role with perhaps more of a playmaker's instinct, something we have seen him do as a more than adequate ball-player.
Wales' need for a second playmaker in Pivac's system is obvious. Halfpenny started the Six Nations in the role before he lost his place in the team.

However, when McNicholl was first brought into the side back in the 2019/2020 season, his role was effectively to work as a second-receiver when Wales looked to put width on it when working across to the opposite wing.
And that would free up Adams to pick and choose his moments in midfield, as demonstrated by a hat-trick from full-back against the rather generous Sharks on the recent Lions tour.
His first that day came from picking a line off Rees-Zammit's carry in midfield, unsurprising given Adams' knack for finding the right moment to strike in an attack and his previous experience in the role with Worcester.
Now, I'm not saying Pivac should definitely start Adams at 15, nor am I sure he will.
But with his two first-choice full-backs out injured - and no guarantee in particular that Williams will be back fit for the second match against South Africa - it could be tempting to try Adams out in the position to see what he can offer from the backfield two years out from a World Cup.
At the very least, Adams' work ethic and rugby brain would make him a safe bet to perform well in the role - maybe better than the other candidates if we're being honest.
Whether that alone justifies moving him from his favoured position will ultimately be down to Pivac.
