First of all, the problem is not new information. It's how you use the information. If your instinct is that Zegras is better than Kakko because he can walk some guys who will get nowhere near the NHL, you are using the new information wrong. You don't properly understand the new information.
And look, if you thought all along that Zegras was better than Kakko, better than Hughes, Turcotte, Dach, Byram, Cozens, all these guys he might now be better then, stick with it. I'm all for people having different opinions, and it's not unrealistic to think he's the best of all these 2019 players. I really don't think there's a huge gap between those two players. But don't tell me that now. It shows that you don't understand the new information if it only comes about now.
It's not just Zegras. It's Byfield, it's Caufield, it's Turcotte, it's Byram, it's Podkolzin, it's Askarov, it's Knight, it's Stuetzle, it's Sanderson. All these guys that, good or bad, have all these hot-takes spewed about them from this tournament. It's as if people are voluntarily saying that they don't watch these players during the season, they will form a season's worth of opinion based on this two-week junior tournament, and they make no apologies for that and don't care how faulty that actually is. Thats my issue with these WJC overreactions, and why I think these few weeks are the absolute lowest standard of discussion you'll see on this website.
