Not sure how it's at all tragic, the bloke has had a reasonably lengthy AFL career earning himself a stack of cash along the way, wanting to go home for the benefit of his family is only understandable.
The reason it's tragic, is that he's currently in career best form after re-inventing himself as a rebounding defender. He was VERY close to getting delisted from the Pies at the end of the 2010 season, with his career at the crossroads His main issue was the huge drop in pay the Pies put on the table, which he thought was an insult given how well he did in 2011. But the Pies had no choice because of the Salary cap squeeze, thanks mainly to Thomas and Pendlebury's management who aggressively used the GWS situation as contract leverage. The situation now is he's probably going to be without a club to go to. Would have thought 250k at the Pies was better than nothing. Perhaps he was given assurance from one of the Freagle teams prior to quitting the Pies. Who knows. Anyway, it hasn't worked out well for Leon. He deserves better than that. Seems like he's received some very poor advice.
