Really depends on your definition of "really good", we've had 3 Origin players this year in Haas, Young and TPJ. Would find it very hard to argue against the first two falling within that definition.
As far as talent goes there would be short odds of Pezet joining that "really good" group at some point in his career, as the 19s Origin demonstrated he's among the best in that age group.
Agree that the Central Coast and probably Mid North Coast has dominated our junior rep sides for a while but there's been a bit of a swing back to Newcastle in the last couple of seasons.
