In expert analysis, the young playmaker has shown that he merits the first-choice spot for the national team's number ten versus New Zealand on Saturday.
Fin Smith delivered without doubt the most impressive defensive performance we have seen by an English fly-half for quite some time.
How he fronted up through regularly completing his tackles versus an aggressive Fijian team was impressive.
His tactical control proved exceptional - he showed a perfect blend of skill and control, and made some strong decisions during moments didn't proceed as expected during the opening period.
His capacity to settle the team strategically and make big calls is something he has really nailed.
In my opinion, Fin Smith is England's primary fly-half and he should begin versus the All Blacks this weekend.
I believe head coach the England coach views it that way as well, because Fin has proven his capability during important international games.
George Ford started last Saturday versus the Wallabies for leadership considerations, and part of that choice was to provide continuity and reward his form from the tour of Argentina.
But England's showing versus the Pacific Islanders was a significant step up from the performance against Australia.
Australia were defeated in Italy on Saturday, therefore we must avoid becoming overly excited about that victory, which should have been more comprehensive considering how off the pace Australia performed.
Fiji, on the other hand, were much more threatening and presented a far tougher test.
Fin Smith remains just 23 - projecting forward two years, alongside Ford pushing him while providing backup, I think Smith will find himself in an excellent position in his career.
Marcus Smith also has to be considered as a possibility at the right time and against the right opposition.
He is developing as a player and is starting to find his feet, though he requires liberty to show his distinctive qualities.
New Zealand brought on their impact player, who scored the decisive try defeating Scotland, and that shows the significance of having individuals capable of creating a real impact as substitutes.
Such type of player can be the deciding factor separating victory the global tournament from failure.
The All Blacks substitute observes the game develop from the bench while considering about how to create a difference upon entering.
His decision-making and mistake frequency have enhanced substantially from his initial professional days.
Should we develop Marcus to be that kind of impactful performer, then having him among substitutes might prove beneficial.
Nonetheless, at the moment I don't think he represents the solution at full-back, so that is a position that is still up for grabs.
New Zealand will kick testing the English defensive line, therefore it must to be impenetrable.
This role requiring transforming into a genuine asset, in defense while regarding of the counter-attack danger.
Currently, I believe Smith functions as full-back at the highest level.
I struggle to see the benefit of playing him there.
I prefer the ball under his control frequently, though I think that should be in the front line, particularly in the final quarter.
There are obviously numerous similarities comparing Ford with Smith.
Smith possesses the ability executing right decisions under pressure - his instincts are not something you can really taught.
I recall as he received the ball at one stage just inside his own half appearing like it could be on if they swung it wide.
However during these milliseconds he thought the team required reversing Fiji round since England were leading points-wise, so he kicked it to pin the opponents and turn pressure.
That's the sort of playmaking securing championships while claiming global tournaments.
He also has that calmness during intensity to organise teammates around him, and the understanding that he mustn't constantly serve to be the first option.
I want to see him given the opportunity to show that at the highest standards soon, similar to the veteran do, especially at domestic matches week in and week out.
During the South American tour, the experienced fly-half similarly excelled during challenging situations, where historically one might suggest there have been times where he didn't fully delivered during extremely tense matches.
I believe we have playmaking options capable of performing the role, but with Fin's defence combined with additional qualities, establishes him as the more complete versatile performer.
This also indicates there's no need to modify your defensive system when you have an assertive player in the fly-half channel, instead of an individual being a little more passive.
One might make a strong case for Ford starting and Fin Smith coming off the bench.
Numerous considerations that go on privately, but whichever way the coaches choose to proceed, it will give the opponents problems.
That has not always been the narrative facing New Zealand, when attention was simply on picking the optimal individual.
On this occasion, either playmaker they choose will pressure New Zealand under real pressure.
Smith's capacity to pick the right kick while delivering enabling possible territorial gains might relieve all the stress off the national team.
