touchy question. Wally Lewis comes to mind but considering he was playing in what was a very high quality brisbane competition when he was at his peak and from memory was a gf winner it is hard to say that if it was in the competition we have known it to be since expansion outside of NSW whether he would have won a premiership.
If you went from say 1988 onwards Hindy's name is the first that comes to mind. Michael Bani a close second
Has anyone said Slater/Smith/Cronk yet?
