The notion of filling our ranks with castoffs from a junior league (not including their ring-ins from elsewhere), that is considerably smaller than our own, is not one that I agree with.
Look at the successful Manly sides of 1976* and 1978**: both used EIGHT Manly juniors out of 15 players in each of those grand finals, to win their respective premierships. With a host of imports that were unknowns/relative unknowns when they joined Manly.
Over time, that is what Manly needs to try and get back to. Not by taking recruiting shortcuts by pillaging other junior districts. I would settle for around half the starting team being local products at some point, in the near to midterm.
The best we seem to do of late is three Urbos and young Hoppa. Or before him, Brad Parker.
*1976: Gartner, Alan Thompson, Ian Martin, Randall, Krilich and Harvey, with Thoroughgood and Willoughby off the bench
**1978: Gartner, Knight (via Wests and Balmain), A. Thompson, I. Martin, Randall, Krilich and Harvey, with Springall off the bench
