According to rugby specialists, the young playmaker has demonstrated that he merits the first-choice spot as England's number ten versus New Zealand on Saturday.
Fin Smith delivered without doubt the most impressive defensive display observed by an English playmaker in several years.
How he fronted up by consistently making defensive hits versus an aggressive Fiji side stood out remarkably.
His tactical control proved exceptional - he showed an excellent balance of finesse and composure, while executing some strong decisions during moments didn't proceed to plan in the first half.
His capacity to settle the team strategically and make big calls is something he has truly mastered.
In my opinion, Fin Smith represents England's primary fly-half and deserves to start versus the All Blacks this weekend.
I think the manager Steve Borthwick views it that way too, because Fin has proven his capability during important Test matches.
The experienced fly-half started the previous weekend versus the Wallabies for leadership considerations, and part of that choice aimed at ensuring continuity and reward his performance during the visit of Argentina.
However, the national team's performance versus the Pacific Islanders was a significant step up compared to the display versus the Wallabies.
Australia were defeated in Italy on Saturday, therefore we must not get overly excited about that victory, that could have been more comprehensive given how off the pace the Australians were.
Fiji, by contrast, proved significantly threatening while offering a far tougher test.
The young playmaker is still only 23 - looking ahead 24 months, with Ford pushing him but also offering support, I believe Smith will find himself in a very strong place as a player.
Marcus Smith also has to be regarded as an option at the right time and against the right opposition.
He is developing as a player while beginning to find his feet, though he requires liberty to demonstrate his distinctive attributes.
The All Blacks introduced Damian McKenzie, who registered the decisive try defeating Scotland, demonstrating the importance of having players who can make genuine influence as substitutes.
That kind of player can be the difference between winning a World Cup from failure.
The All Blacks substitute watches the match unfold while substituted and thinks regarding ways to create a difference when he comes on.
His decision-making and mistake frequency have enhanced substantially since his early career.
Should we develop Marcus to be such type influential player, then having him in the backfield could be valuable.
Nonetheless, currently I don't think he represents the solution in the number fifteen position, so that is a role remaining up for grabs.
The All Blacks will kick testing England's defensive line, therefore it must remain watertight.
This role requiring to become a genuine asset, in defense and in terms of the counter-attack threat.
Currently, I don't think Smith is a full-back in top-tier rugby.
I find it difficult to identify the advantage fielding him there.
I want possession in his hands frequently, but I believe that should be among starters, especially in the final quarter.
Clearly there exist numerous similarities between Ford and Fin Smith.
Smith possesses the capacity executing right choices during tense moments - his natural reactions represent traits that can be taught.
I recall as he received possession at one stage within his own half appearing like it could be on if they swung it wide.
However during these milliseconds he calculated they needed to turn Fiji round since England were leading points-wise, so he kicked to pressure them back and turn pressure.
This represents the type of playmaking that wins championships while claiming World Cups.
He additionally possesses composure under pressure directing teammates around him, and the understanding that he doesn't constantly serve as primary receiver.
I hope to witness him receiving the opportunity demonstrating this at elite standards soon, just as we have seen George Ford accomplish, particularly during domestic matches repeatedly consistently.
During the South American tour, Ford also stood up during challenging circumstances, previously you could argue there have been times where he didn't fully delivered in the very highest-pressure games.
I think England possesses two fly-halves who can do the role, but with Fin's defence on top of additional qualities, establishes him as the better-rounded all-round performer.
This also indicates you don't have to modify the defensive structure while fielding someone aggressive occupying the playmaker channel, instead of an individual being somewhat reserved.
You could also present compelling arguments for Ford starting and Fin Smith coming off substitution.
There are so many factors that go on behind closed doors, but whichever way the coaches choose to proceed, this will present the opponents problems.
This hasn't consistently represented the narrative against the All Blacks, when attention concentrated solely on selecting the right player.
On this occasion, either playmaker selected can put the All Blacks significantly.
Smith's capacity selecting optimal kicks and execute enabling possible territorial gains can take all the stress off England.
