An actual answer:
From my findings a couple months ago (and depending on your definition of "victorian", using a fairly loose one here as details on the private life of fringe players are next to non existent) 20 Victorians have played in the NRL, 16 having a Storm contract at some point.
As far as I am aware there are none currently, as Young Tonu just this week left the Titans for the Melbourne Rebels
If you want the names and their NRL Vic clubs find my posts about it in other threads
But either way the NRL isn't a representative comp so it doesnt matter, the Storm aren't an origin side, and it's up to the NRL, not the club, to be better investing in juniors and engagement in the state
