Look you're right. And it's easy to get sucked into the pile-on. How much of that is jealousy and how much is legitimate, founded criticism? I've seen him nancy about a few times when it comes to the crunch. It's not a great look - for him, or anyone who does it. But as you say, he is still a boy. As I said, he's a matchwinner right now - the scary thing is he could be even better if he starts committing his body to the contest.
RE jealousy - how many clubs would love to receive a matchwinner for peanuts due to the father/son rule? I think a bit of the criticism sometimes stems from that.
While the hate is excessive, by the same token, the gushing praise he receives for the most run-of-the-mill acts on-field is nauseating. I think a large part of the resentment certainly stems from this. But that's not his fault. If anything it's a blight on the AFL media, and their prioritising of clicks and sensationalist tripe over proper news and analysis - and a textbook example of the current shambolic state of AFL media.
