The clearest marker is the girls' reported 5-0 league record. That matters because unbeaten teams at this level rarely rely on one hot day; they tend to control the rhythm of a whole campaign.
The update says the run continued through the knockout rounds:
That combination - clean nerve in key moments and the ability to finish the job - is usually what separates champions from strong regular-season sides.
The report also paints a picture of a well-balanced team rather than a one-player squad.
That spine matters. School teams can swing wildly from game to game, but sides with speed up top, composure in midfield and defensive protection tend to hold their level. St Mike's appear to have found that mix at the right time.
The boys' title arguably adds another layer. The update says many of the squad met for the first time at the opening practice, having come together from across Perth County. Building chemistry quickly is difficult in any age group. Winning while doing it points to a squad that reportedly adapted fast and played selflessly.
That is why the double stands out. One title can come from momentum; two usually reflect a wider school standard. The next storyline will be whether St Mike's can turn one golden season into the start of a lasting football habit.
