Yet Metro's ultimate goal is to get young men who might otherwise leave the game to stay involved and think about Whanganui adult club rugby in a couple of years, so Malcolm said it was a "thrill" for them to have this kind of encouraging performance.
"The biggest thing for us, we've got two guys in there, it's their first year of rugby.
"There's also two guys that haven't played since Under-16 ... and five to seven coming back from injuries."
When Metro play their home games at various grounds around town, the Tasman Tanning Premier coaches who keep an eye on them during their own squad warm-ups will want to draw a pencil mark around the name of fullback Terangatira Waitokia.
The young speedster scored the first two tries of the game and eventually made it four as the gaps opened up every time he entered into the backline.
Lock Sean Van Der Lubbe came into his own late in the match when Marist were out on their feet, powering over for consecutive tries, while both the props in Keanu Puki-Kaa and Laurence Webber dotted down, even if they would bear the brunt of some hard tackling and need ice packs on the sidelines.
Preparing for physicality was one lesson Metro need to remember as Marist scored two tries off the back of grinding by the likes of their big prop J Leno.
But it's clear when Metro can play their game that they love to run - spotting the gaps and rapid changes of direction their opposition could not handle.
Scoring so many tries gave Metro a chance to rotate goalkickers for some practice with first-five Hareangi Meihana relinquishing the role to three teammates at different stages.
