Interesting comments by notorious groomer/poacher O'Sullivan:
Interesting that he doesn't mention winning Harold Matts, which is where rich clubs poach many of their SG Ball players from. Also interesting that winning SG Ball certainly seems to work for some clubs as a precursor to NRL success. Here's the list of SG Ball premiers, runners up and minor premiers of the past 15 years:

It's fair to say that having strong SG Ball teams has been very beneficial for the Roosters (O'Sullivan's old club) and Bulldogs (who were strong between 2012 and 2014) and maybe Souths and Cronulla, but less so for everyone else. It's probably worth noting though that the 2016-17 teams would only just be starting to reap the benefits, while the players from the 2018 SG Ball season would be no older than 21 this year.
