pretty sure that journey is more or less complete.
But having said that, the footy public is a pretty fickle beast. Wayne Carey is back, sins absolved. Give it 10 years and they'll no doubt drum up some kind of redemption narrative for him
You know that scene in Goodfella where the Don hands Ray Liotta a wad of cash and says "now I have to turn my back on you"? Hird won't be back. Carey messed up but he never messed with the boys club that run the AFL.
