The try-scoring debut of Johnny McNicholl has given Wayne Pivac and the Welsh public plenty of food for thought.
Will he feature in the Six Nations? If so, who drops out? The likely name is George North - who often comes in for criticism.
During the World Cup, fans were often questioning why North wasn't doing more during Warren Gatland's bid for the Webb Ellis Cup. But were those complaints fair?
Can the accusations be proven or are they myths? And what the future might hold for the 27-year-old.
'George North isn't the player he once was'
Let's start with the big one. This is one that gets banded about quite a lot.
While only 27, there are some who believe the Ospreys winger is a spent force. Many wouldn't go quite that far, but would argue that North isn't quite reaching the heights he once was.
Even his former Wales coach, Warren Gatland, said as much in his recent autobiography.
"George remains a quality player to this day, but he was at his best between 2011 and 2014 - big, physical, fast, fearless... as good as anyone in the world," wrote Gatland.
"Opponents could take to the field knowing everything there was to know about him and still have no answers to the problems he posed.
"That's the mark of a great rugby player and at that point in his career, before the injury problems kicked in, George was touching greatness."
Fair enough. And it's hard to qualify whether North is a waning force through numbers alone.
But, if tries are a winger's currency, then North has actually only upped his game since 2014.
19 tries in 45 games between 2011 and 2014 left with a strike-rate of a try every 2.37 games.
Since the turn of 2015, he's scored 21 in 42 matches - or one every two games in simpler turns.
Contextually, of the tries he's scored between 2010 and 2014, five of the 19 came against the big three southern hemisphere teams (three against Australia and two against South Africa).
Since 2015 though, he hasn't touched down against either Australia, New Zealand or South Africa. For added context, eight of those 21 tries have come against Italy - a team he had never scored against between 2010 and 2014.
The list of teams give the suggestion of a flat-track bully. That's not necessarily a bad thing for a Test winger.
Despite the added context of the teams he's scored against, his try count suggests that he's still the player he was six years ago where it matters. Of course, anecdotal evidence and perceived wisdom might say otherwise.
And tries of course aren't the only facet of a winger's game, and five-point scores alone don't prove or debunk the above notion.
'He doesn't go looking for work'
This is probably the main accusation laid at North's door when it comes to specific facets of his game that aren't up to scratch these days.
It's a common-held view that when North isn't heavily involved in a game, it's because he's not coming off his wing, looking for work often enough.
But I'm not sure that's the case. Sure, there are matches where he might only get the ball four or five times - take the World Cup clash with Fiji earlier this year, for example - but it's not necessarily a case that he's hiding on the wing.
Between 2010 and 2016, his average number of touches of the ball was around 10 per game. Having had 19 touches on his barnstorming debut against South Africa in 2010, he matched that tally just once in the following six years and 56 caps - against Argentina in 2012.
So it's little surprise that when you pick random games from different eras of North, the numbers are close to the 10 mark.
Take the Six Nations victories over England in 2012 and 2019. Seven years apart but from watching both games, you can see that the numbers are relatively the same.
He had 11 touches of the ball this year. One more seven years prior.
But both times, he carried five times off his wing and just twice on his touchline. As a side note, it's worth adding that both this matches saw North play on the left wing - where he looks most comfortable.
North gets the vast majority of his touches away from his wing. How he gets those touches has changed a little over the years.
In the 2012 fixture, most of North's in-field carries come from inside balls or pull back passes from the scrum-half or fly-half, giving North space or soft shoulders to attack.
In 2019 however, most of his carries away from his wing are either pick-and-goes from the base of rucks or one-up carries off the scrum-half. Wales lack big ball-carriers at present and using their potent strike-runners in and around the rucks can be a good way of getting over the gainline.
That doesn't always help the perception of North. You get less big breaks, more incremental gains.
He appears to spend less time taking passes off the fly-half's shoulder, more time shadowing rucks, looking for work around the fringes. The challenge has always been getting involved as much as possible.
But conversely, there's little point getting him touches for the sake of touches. Quality most certainly comes before quantity on that front.
And in recent times, Wales have found using him in tighter channels helps provide more effective carries - even if we probably see him in open space less often than we once did.
It's basic logic in many ways. The best way of using North is getting him as many touches as possible where he dictates the terms of contact. If you can manipulate defenders in midfield so North can dictate the contact he takes there, great.
If not, having him pick-and-go at pace - where he can identify opportunities himself to get over the gainline and take defenders with him - is a good option.
What you can say, in both games, is that North strikes a decent balance between coming off his wing and going looking for work. In both matches, he appears patient on his wing - holding the touchline until he needs to come into midfield.
It could be argued that following rucks rather than running off the ten could be chasing work a little too hard, but I think that's more to do with how Gatland wanted to use his big ball-carriers in the last year.
For added context of how North's contribution compares to other wingers in Test rugby, just compare his involvement with team-mate Josh Adams.
The pair's numbers hardly differ across 2019. North averaged 5.25 carries per game, while Adams was making 5.47.
Hinting that North was running in more congested traffic, North beat 2.33 defenders per game while Adams beat just 1.6. That idea is backed up by the fact that Adams made 1.77 clean breaks per game to North's 1.08.
'He's defensively and aerially suspect'
Another complaint leveled at North.
'He can't defend and he can be targeted in the air'.
Again, it's a rather lazy perception.
The aerial game is something North has worked on during his career. In the Six Nations clash with England this year, when much had been made of how England's kicking game would isolate North, he claimed three high balls from three attempts.
Like any winger defending a cross-kick, he can be caught flat-footed against an opposition player running at pace but that can hardly be held against him. Conversely, he's a solid weapon in the air going forward.
His defence too has improved - with the numbers this year much more favourable than before.
There's only so much that can be read into tackle statistics. After all, one dominant missed tackle that forces a player backwards into another dominant completed tackle is often better than a passive tackle - even if the number don't show it.
But this year, North has attempted 58 tackles - missing just 7. That 88% success rate is considerably better than the 65% he was working at in 2017.
He's still fallible at times - as shown by his error to allow Yoann Huget to score in this year's Six Nations opener. But a defensive liability? No.
Another part of his defensive game is his work at the breakdown.
No Welshman secured more turnovers in this year's Six Nations than him and his ability to read when to commit to the breakdown and when to move away is a real strength in terms of snuffing out opposition attacks and even winning penalties out wide.
'Johnny McNicholl should be pushing North for a starting spot'
After crossing for a score against the Barbarians, a few fans and pundits have raised the point that McNicholl will be pushing North for a starting spot come the Six Nations.
It's impossible really to know at this stage as it all depends on what Pivac opts to do between now and February.
But what we can do is look at the strengths and weaknesses of the two players and see which one might suit Pivac's style of play better.
Like North, McNicholl works off the ball - but his added ball-handling skills offer an added dimension that Wales can make use of.
Take Ken Owens' try against the Barbarians, he tracked across the field - offering himself off the fly-half's inside shoulder as Wales worked their way from right to left.
As Wales moved it back left, McNicholl, now in midfield, stepped up to take a miss-pass from Jarrod Evans. The Barbarians winger spotted that Wales have numbers and was forced to fly out of the line to try stop McNicholl man and ball.
McNicholl read this and got his hands free to give a pass out to Leigh Halfpenny as soon as he received Evans' pass. The ball was moved to the space and it was a walkover for Owens.
It's questionable whether North has that same ball-handling ability. He has shown he can offload well, but does he have the quick hands to give a pull-back pass or offload under pressure when Wales look to exploit small pockets of space in the wide channels?
That's debatable. Pivac's gameplan is likely going to involve quick, accurate passes in the wider channels and outside backs offering themselves as ball-playing first-receivers.
We know McNicholl can do this. The question is, can North?
The other facet where McNicholl is impressive is his strike-rate. Since joining the Scarlets in 2016, he has touched down 38 times in 73 appearances. That's one try every 1.92 games.
In the same amount of time, North has managed 16 tries in 45 domestic matches - averaging one every 2.81 games.
It's early days and the 91 caps of North will count for something. But, knowing how Pivac is likely to play, it's more than reasonable to say that North's place in the side will be tested by the new man on the scene.
