In expert analysis, the young playmaker has demonstrated why he deserves the first-choice spot for the national team's fly-half against New Zealand on Saturday.
The Northampton Saints star delivered without doubt the best defensive performance observed from an England fly-half for quite some time.
How he fronted up by consistently making defensive hits versus a physical Fiji side stood out remarkably.
His game management was also immense - he showed a perfect blend of finesse and composure, while executing several crucial choices during moments were not going to plan in the first half.
His capacity to settle the team tactically and make big calls represents an aspect he has truly nailed.
In my opinion, Fin Smith represents England's primary fly-half and he should start against New Zealand this weekend.
I believe the manager Steve Borthwick views it that way too, since Smith has proven he can perform in big international games.
George Ford began last Saturday versus the Wallabies for leadership reasons, and part of that choice aimed at ensuring consistency while acknowledging his performance from the tour to South America.
However, the national team's performance versus the Pacific Islanders represented a marked improvement compared to the display versus the Wallabies.
Australia were defeated in Italy last weekend, therefore we must avoid becoming overly excited about that victory, which should have been by a larger margin given how below par the Australians performed.
Fiji, by contrast, proved significantly dangerous and presented a far tougher challenge.
Fin Smith remains just twenty-three - projecting forward 24 months, alongside Ford pushing him but also offering backup, I think Fin will be in an excellent position as a player.
The Harlequins star also has to be considered as a possibility when appropriate and against the right opposition.
He's progressing in his career while beginning to find his feet, but he also requires liberty to demonstrate his unique attributes.
The All Blacks brought on their impact player, who registered the match-winning try to beat the Scottish team, and that shows the importance of having players who can make a real impact as substitutes.
Such type of player can be the difference separating victory a World Cup or not.
The All Blacks substitute observes the game unfold while substituted while considering about how he can make a difference when he comes on.
His choices and error rate have enhanced significantly since his early professional days.
If we can get Smith to be that kind influential player, then having him among substitutes could be beneficial.
Nonetheless, at the moment I believe he represents the solution at full-back, making it a role remaining up for grabs.
The All Blacks will kick to challenge the English backfield, therefore it must to be impenetrable.
This role requiring to become a genuine asset, in defense and in terms offensive transitions threat.
Right now, I believe Marcus is a full-back at the highest level.
I struggle to see the benefit fielding him there.
I want possession in his hands as much as possible, though I think that should be in the front line, especially during the last 20 minutes.
Clearly there exist a lot of similarities comparing Ford and Fin Smith.
Smith possesses the ability to make the correct choices under pressure - his instincts represent traits you can really taught.
I remember as he received possession during one phase within his own half appearing that opportunity existed should they swung it wide.
But in those milliseconds he thought they needed to turn the opposition as we are up on the scoreboard, therefore he punted to pressure the opponents applying pressure.
This represents the type of fly-half play securing championships while claiming World Cups.
He additionally possesses composure under pressure directing teammates around him, and the understanding that he doesn't constantly serve to be the first option.
I want to see him receiving the chance to show that at the highest standards soon, just as we have seen George Ford do, especially at club level week in and week out.
In Argentina, Ford also stood up in difficult circumstances, where historically one might suggest there have been times where he didn't fully done so in the very highest-pressure games.
I believe we have playmaking options capable of performing the role, but with Fin's defence combined with everything else, establishes him as the better-rounded all-round performer.
This also indicates you don't have to modify your defensive system while fielding someone aggressive in the fly-half position, rather than an individual being somewhat passive.
One might make a strong case favoring Ford beginning with Smith entering from substitution.
There are so many factors that go on behind closed doors, but whichever way the coaches choose to proceed, this will present New Zealand difficulties.
This hasn't consistently represented the narrative facing New Zealand, where the focus concentrated solely on picking the optimal individual.
This time, either playmaker they choose will pressure the All Blacks significantly.
Smith's capacity selecting the right kick and execute enabling possible 50-20 might relieve all the stress off England.
