"We did really well to start the game, we set a platform and in games like this you just can't afford to let off, you've got to stay on top of your game and we didn't do that."
As they tended to do throughout the season, Boxon took a bit of time to warm up and let a quick try in to Dragons hooker Jesse Pirini, who burrowed over from close range.
But Boxon came back with a vengeance.
First to reply was outstanding halfback Bernard Matthews, who led by example all game.
He put in a delicate little grubber, which hit the post and sat up perfectly to collect and dot down.
The score was 6-6, but it didn't stay that way for long as Tautahi Rawiri kicked a penalty goal and moments later Matthews scored his second showing some fancy footwork from close range.
Not all was good for Boxon though as in the lead up play five-eighth Corey-Lee Robertson went down with what looked to be a knee injury and was carried off the field.
Despite this, the floodgates opened.
Boxon were spurred on by the scoreline and the Dragons, who flew out of the gates aggressively, now looked very tired.
Boxon captain Woody Martin scored next, making it look easy from close range and breezing by a bunch of exhausted defenders to extend the lead to 20-6.
But the Dragons fire didn't burn out, they continued to fight and interchange player Jonathan Fidow's blockbusting run forced a line break and eventually led to him scoring.
With another Boxon penalty leaving the half time score at 22-12, Reweti could be forgiven for thinking his side were in control and that confidence would have only grown after the break.
Ritchie Graham and Matt Everleigh-Rangi scored back-to-back tries to open the second half, giving Boxon what seemed to be an insurmountable 22 point lead.
But then it happened, the collapse, a reversal of roles between the teams from the first half as now it was Boxon who were tired and as a result, their discipline abandoned them.
The Dragons momentum began with Tieimi Ransfield, who put in a bruising run straight through two defenders, then stepped fullback Emitai Logadraudrau to score.
Suddenly Boxon were on the back foot, as Pirini went in for his second, then Dylan Hall was in, and Ransfield went in again and the scores were tied at 34-all.
A change of goal kicker for the Dragons saw winger Chance Te Uira miss the conversion to take the lead, but it didn't matter, Boxon were exhausted.
With about six minutes remaining, Rawiri was penalised for a dubious ruck interference, the Dragons reinstated Hall to kick the goal and he nailed it to incredibly give his side the lead.
Boxon were shattered and Reweti could only watch on as his side let in one last heartbreaking try to Te Uira, converted by Hall, to seal the deal at 42-34.
Reweti said the Dragons had been there too many times for his side to let mistakes slip into their game.
"You've got to finish strong in big games like this and unfortunately we didn't, a bit of a lack of experience let us down, but we'll be back bigger, better and stronger next year.
"I'm very proud of our boys, it's hard to take a loss, but looking back on the season, we've come a long, long way, not just in terms of playing, but of being a team and being a brotherhood.
"This was my first year as a coach, I've learned a lot, especially in this game today, I'll be back next year for sure, I won't be leaving until I get that win."
