Further confirmation came when he made the New Zealand under-20s and Auckland squads but 2015 was written off due to a badly damaged knee that had to be rebuilt. He returned to action only to suffer the same fate and 2016 disappeared, too.
Blues coach Tana Umaga, as one of the professional era's best midfielders, is about as good a judge of talent there is, and was willing to pick 21-year-old Faiane in this year's squad despite his lack of football in the past two years.
Faiane's promotion to the starting team is further reward for his performances off the bench in recent weeks and also driven by Umaga's desire to see if his protege can deliver with a No 12 on his back.
"TJ is the consummate team man," said Umaga. "He brings a lot of energy and does all he can for his team and teammates. He's very studious around the game and has all the skills we like in a 12. TJ has been good for us coming off the bench. He has done everything we've asked of him and he's been a year in the making.
"He's earned the right to have a crack. With the amount of games Rieko has had, it gives us an opportunity to see TJ and we believe he has the ability to play at this level for a long time and the teams he has made previous to this shows that.
"And George is playing well, too. We've got a lot of midfielders and trying to fit them into two spots is impossible."
However hard the midfield selections are now, they will become harder when Sonny Bill Williams returns. The veteran midfielder still doesn't have a scheduled return date from his Achilles tendon surgery.
The hope is that he will appear some time in April but Umaga said it is a day-by-day scenario with Williams as he builds his running load and then waits to see how his body reacts. The Blues are eager to get him back but won't push him too soon.
Williams' direct running, aggressive defence and offloading game will open multiple attacking avenues for the Blues. Once he recovers, though, the challenge for the Blues is going to be finding the right combination of players across their backline to get the best out of their attacking game.
