In expert analysis, the young playmaker has shown why he deserves the first-choice spot for the national team's fly-half versus New Zealand this weekend.
Fin Smith produced without doubt the best defensive performance observed from an England playmaker for quite some time.
His courageous approach through regularly completing defensive hits versus an aggressive Fijian team stood out remarkably.
His game management proved exceptional - he demonstrated a perfect blend of finesse and control, while executing several crucial choices during moments were not going as expected during the opening period.
His ability to calm the team tactically and make important decisions represents an aspect he has truly mastered.
In my opinion, the young fly-half represents England's primary fly-half and deserves to begin against the All Blacks this weekend.
I think head coach Steve Borthwick sees it that way as well, because Fin has demonstrated his capability in big international games.
The experienced fly-half began the previous weekend versus the Wallabies for leadership reasons, and part of that decision aimed at ensuring consistency and reward his performance from the tour of Argentina.
However, the national team's performance versus the Pacific Islanders represented a marked improvement from the performance against Australia.
Australia lost in Italy last weekend, so we should not get too carried away with that win, that could have been more comprehensive considering how off the pace Australia performed.
Fiji, on the other hand, were much more dangerous while offering a far tougher test.
The young playmaker remains just twenty-three - projecting forward two years, alongside Ford challenging him while providing support, I think Smith will find himself in an excellent place as a player.
Marcus Smith must also be regarded as an option when appropriate and against the right opposition.
He is developing in his career and is starting to find his feet, though he requires liberty to demonstrate his distinctive attributes.
The All Blacks introduced their impact player, who scored the match-winning score to beat Scotland, demonstrating the significance of possessing players who can make genuine influence from the bench.
Such type of presence might represent the difference separating victory the global tournament from failure.
The All Blacks substitute observes the match develop from the bench and thinks regarding ways he can make an impact upon entering.
His decision-making and error rate have improved significantly since his early professional days.
Should we develop Marcus to be such type of impactful performer, then having him in the backfield could be beneficial.
Nonetheless, currently I believe Marcus is the answer in the number fifteen position, so that is a role remaining unclaimed.
New Zealand will kick to challenge England's defensive line, so it has to be impenetrable.
It is a position that needs transforming into a real strength, in defense and in terms of the counter-attack danger.
Currently, I don't think Smith is a full-back in top-tier rugby.
I struggle to see the benefit of playing him in that position.
I prefer possession in his hands frequently, though I think this should occur among starters, particularly in the final 20 minutes.
There are obviously numerous similarities comparing Ford with Smith.
Fin has the ability to make right decisions under pressure - his natural reactions are not something that can be taught.
I recall as he received the ball during one phase just inside his own half and it looked that opportunity existed should they swung it wide.
However during these milliseconds he calculated the team required reversing the opposition since England were leading points-wise, so he kicked it to pin them back applying the screw.
This represents the type of playmaking that wins championships and wins global tournaments.
He additionally possesses that calmness under pressure to organise the players around him, and the understanding that he doesn't always need as primary option.
I hope to witness him receiving the opportunity demonstrating this at elite standards soon, similar to George Ford accomplish, especially at club level repeatedly and week out.
During the South American tour, the experienced fly-half also stood up in difficult circumstances, previously one might suggest there have been times he has not quite done so during extremely tense games.
I believe we have two fly-halves capable of performing the role, but with Fin's defence on top of additional qualities, it makes him the more complete versatile performer.
This also indicates there's no need to modify the defensive structure while fielding an assertive player in the fly-half channel, rather than an individual being a little more reserved.
One might present compelling arguments for Ford starting and Fin Smith coming off the bench.
There are so many factors that go on privately, but whichever way the management choose to proceed, it will give New Zealand problems.
That has not always been the situation against the All Blacks, when attention concentrated solely on picking the right player.
On this occasion, whichever fly-half selected will pressure the All Blacks significantly.
Fin's ability to pick optimal kicks and execute for a potential territorial gains might relieve pressure away from England.
