Fair enough mate. I'm a bit of a stickler when it comes to our past players (mostly). I do have a tendency to defend them to the hilt. I just can't bring myself to think Brett would give anything but 100%.
That said, "something" was wrong to be sure, but for mine, it was that he had a knee "cleaned out" yet was back there playing weeks after - yuck. I'd be a dead set cripple.
I understand where you're coming from (and others) though. I will only ever hold that man on a pedestal - these guys playing footy over the past half a decade got me through some pretty rough times in life.
That's why footy is more than just that (for me). It's a release. It's entertainment, and something to get your mind off the tougher things that hit you sometimes. Brett had a part in that, so he'll have my support until the day he kicks the bucket.
