That's all well & good, but most of a player's development still happens in their first couple of years on the list. If they haven't developed enough to earn a debut game in that time, they generally don't go on to succeed further down the line. That holds true, regardless of player type/role, stage of initial development (i.e. project players) or injuries.
You can make all the excuses you like, or reasons why Doedee will be different, but the facts are very simple. Very, very, few players who were drafted in the 1st round, and failed to debut in their first 2 years, have gone on to have successful AFL careers. There's no escaping this - it's a historical fact.
If Doedee plays 100 AFL games, he will be just as big a statistical anomaly as someone who plays 400+ AFL games, or someone who is still playing AFL at the age of 40.
Any chance of you blokes agreeing that you don't agree?
