Interesting - the public team lists for both those clubs [Uni and Easts] imply their two coaches did actually rate them as best in their positions (Tancred and Nicolle) in their respective 1st colts' - from round 8:
The team lists publish Tancred and Nicolle following a similar path - Colts 1s from around Game 8, then starting Colts 1s for the rest of the season [Tancred in Uni Colts #4/5 or #8 - Nicolle in Easts Colts at #7 - Easts seem lucky with 2nds colts final that Nicolle had played enough 2s games to qualify - 1s Colts were knocked out in finals round 1 [team list has Nicolle starting at #7 with Di Staso #6].
Tancred seems to have been on the bench for the Uni finals rounds - maybe injury or simple selection decisions?
But to your point, the team lists show both were in first-choice forward packs in club land - and started their respective Colts 1s games from round 8/9 onwards - looks like simple meritocracy [the way it should be] in club land, which was then rewarded with rep selection.
The question I ask myself - why were they not 1st choice from the beginning of the season - perhaps they were relatively unknown? That is the beauty of meritocracy is my guess - when employed correctly.
