In expert analysis, Fin Smith has shown why he deserves the first-choice spot as England's number ten against New Zealand this weekend.
The Northampton Saints star delivered arguably the most impressive defensive display we have seen from an England playmaker for quite some time.
How he fronted up by consistently making defensive hits versus an aggressive Fiji side stood out remarkably.
His tactical control was also immense - he demonstrated a perfect blend of skill and control, while executing several crucial choices when things were not going to plan in the first half.
His ability to calm the squad strategically and make big calls represents an aspect he has truly nailed.
From my perspective, Fin Smith represents England's primary playmaker and he should start against the All Blacks this weekend.
I believe head coach Steve Borthwick sees it that way as well, because Fin has proven he can perform in big international games.
George Ford started last Saturday versus the Wallabies for leadership reasons, and part of that choice aimed at ensuring consistency and reward his form from the tour of Argentina.
However, the national team's performance against Fiji was a significant improvement compared to the display against Australia.
Australia were defeated in Italy on Saturday, therefore we must not get overly excited with that win, which should have been by a larger margin given how below par the Australians were.
The Fijian team, by contrast, were much more dangerous while offering a far tougher challenge.
Fin Smith remains just twenty-three - projecting forward two years, alongside Ford pushing him but also offering backup, I think Fin will be in an excellent position in his career.
The Harlequins star also has to be regarded as a possibility when appropriate and versus suitable opponents.
He is developing in his career while beginning to find his feet, but he also requires liberty to show his distinctive attributes.
The All Blacks introduced Damian McKenzie, who scored the decisive score defeating the Scottish team, demonstrating the significance of having individuals who can make a real impact as substitutes.
Such type of player might represent the difference separating victory a World Cup from failure.
McKenzie observes the match unfold from the bench and thinks regarding ways to create a difference when he comes on.
His choices and error rate have improved substantially from his initial career.
If we can get Smith to be such type influential performer, then having him in the backfield could be valuable.
Nonetheless, at the moment I believe he is the answer at full-back, making it a position that is still unclaimed.
New Zealand are likely to punt to challenge England's backfield, therefore it must remain watertight.
It is a position requiring to become a genuine asset, both defensively while regarding offensive transitions threat.
Currently, I believe Marcus functions as full-back at the highest level.
I struggle to see the advantage fielding him there.
I prefer the ball in his hands as much as possible, though I think this should occur in the front line, especially during the last quarter.
Clearly there exist numerous similarities comparing Ford with Smith.
Fin has the ability executing right decisions under pressure - his instincts are not something you can really taught.
I recall as he received the ball during one phase just inside his own half and it looked like it could be should they spread play.
However during these split-seconds he thought they needed reversing the opposition since England were leading points-wise, so he kicked it to pin them back and turn pressure.
That's the sort of playmaking securing titles while claiming World Cups.
He additionally possesses that calmness during intensity to organise teammates nearby, and the understanding that he doesn't constantly serve as primary receiver.
I hope to witness him receiving the opportunity demonstrating that at the highest level next week, similar to George Ford do, particularly during domestic matches repeatedly consistently.
During the South American tour, Ford also stood up during challenging circumstances, where historically you could argue there have been times where he didn't fully delivered in the very highest-pressure matches.
I think England possesses playmaking options capable of performing the role, though Smith's defence combined with additional qualities, establishes him as the more complete versatile performer.
It also means you don't have to adjust your defensive system when you have someone aggressive in the fly-half position, rather than an individual being a little more passive.
You could also present compelling arguments favoring Ford beginning and Fin Smith coming off substitution.
Numerous factors occurring behind closed doors, but whichever way the coaches choose to proceed, it will give New Zealand difficulties.
That has not always been the situation against the All Blacks, when attention was simply on picking the optimal individual.
This time, either playmaker selected will pressure New Zealand under real pressure.
Smith's capacity selecting the right kick and execute enabling possible territorial gains might relieve pressure off the national team.
