He over delivered in his first test and through no fault of his own, had set public expectation a little too high which may have prevented many from seeing Sopoaga's real international career trajectory.
The truth is that Sopoaga may not have made the All Blacks squad this year had he stayed in New Zealand.
His place was under threat and he could see it. Coming up fast on the rails was Richie Mo'unga, a younger man and arguably a better player.
Trying to project 12 months ahead, Sopoaga would have been able to see that a year out from the World Cup, Mo'unga may well have the more compelling case for inclusion.
With Beauden Barrett a cast-iron certainty and Damian McKenzie's ability to play at fullback and change the pace and nature of any test off the bench, those two were always going to rank ahead of him.
The third first-five spot would be a head-to-head between Sopoaga and Mo'unga and so when Wasps came knocking early this year, the decision to leave wasn't that hard for the former.
He couldn't see when he would actually start a test in 2018 or 2019 and he couldn't even be sure that by June he'd still make the squad.
With Wasps reportedly offering him about a $1 million a season and his earnings likely to be about a third of that in New Zealand, he decided to go.
He decided the lure of the All Blacks jersey was no longer enough to keep him in New Zealand – just as Charles Piutau, Steven Luatua and Malakai Fekitoa had come to the same conclusion before him.
But Sopoaga's attempts to suggest the All Blacks have generally lost their holding power is a total misrepresentation of the truth.
If anything, the lure of the jersey has become greater, and the prevailing trend is for players not to walk out on their test careers early, but to commit for longer.
Richie McCaw, Dan Carter, Ma'a Nonu, Conrad Smith and Tony Woodcock never lost their love of the jersey. Kieran Read is going to be here until the end of his career and Ben
Smith has given the best of his years to New Zealand. Sam Whitelock and Brodie Retallick will probably lock in until the 2023 World Cup, as will Beauden Barrett and maybe Aaron Smith will too.
Those who have confidence they are frontline All Blacks – near certainties or high probabilities to be picked - are willing to commit for the duration of their careers.
The All Blacks haven't seen a first-choice player leave prematurely in the last 10 years and that is perhaps the problem for those fringe players such as Sopoaga.
The view from that middle tier of the playing base is different. Players there can see that their pathway to the starting team could well be blocked for eternity.
They also know that New Zealand's system keeps producing and that seemingly in no time, there will be someone pushing up from below.
The more the top tier want to stay the easier it becomes for the lower to be persuaded to leave and while Sopoaga may have sent the UK media into a frenzy with his claims that the floodgates are about to open and All Blacks will be flooding into Europe, back here neither his claims nor his departure have left much of an impression.
Every month or so the players New Zealand really wants to stay announce they are staying and while there are predictions of doom and gloom about what the future looks like, the present suggests the All Blacks are doing just fine.
