"I knew we could front them from the start, even though they toweled us up in the first round."
However, Reweti asked his team to up the pace in the second half, only to watch it all fall apart in the back end of the game as the Cobras ran in three converted tries in quick succession.
"Just composure, we had to hold ourselves but somehow we get these 10-15 minute lapses.
"We had it in the bag, the boys couldn't capitalise."
Boxon still could have stolen the game back after the Cobras' last try as they swept up to the home team's tryline within three tackles and earned a penalty.
Unfortunately, Reweti said the player holding the ball had a rush of blood to the head, because even as Koro was walking forward to signal they would take the kick the player made a quick tap and was tackled on the last play.
Boxon's next game is in Otaki against Whiti Te Ra Brothers 1 on Saturday, kickoff 1pm.
