It's got nothing to do with race. As was mentioned in the Chris Knights thread, as soon as his brother became a pilot, we was less settled, but before that he was fine. I don't think you can underestimated the difference between living in a remote outback area and living in a city full of skyscrapers. If there are others there that you can relate too, I'm sure it's made a whole lot easier. I would have thought LJ was a little different from any other player indigenous or otherwise. His changing landscape has surely been far more drastic than many others. For that reason, Aaron, as the more senior player, plays a big part in his life.
Furthermore, when I used the "indigenous angle" line, I wasn't just referring to keeping LJ, I was also alluding to the Aaron Davey scholarship, for indigenous players.
