So no one else has heard of Kevin Schubert? 19 tests for Australia, whilst playing both in Wollongong and for Manly-Warringah during the CLub's early days.
Schubert, Jones and Krilich (and probably Cochrane) were our greatest hooker forwards, when that still meant something. Ballin will probably be there by the time he retires, but as we know the 'hooking' is not really part of the deal anymore.
Brown and Gray only filled the position briefly and/or sporadically, although there is no denying their respective abilities.
