I don't think it was mentioned, but Olausson got traded to Oshawa in Ritchie's D-1 so I'm sure the Avs saw a lot of Ritchie.
He led the '22 Hlinka Gretzky tournament in scoring (on a team with Benson/Yager/Barlow/etc). I thought he was more opportunistic than dominant in the tournament. Just an ok OHL season. Some may say underwhelming, but he showed well in my viewings. Pretty solid under 18s mostly playing wing with Celebrini and Wood.
I'd say there are decent to good odds that Richie puts up 100 points next year and decent chance he makes the world junior team. IF they are planning to make a big push next year and are considering using Ritchie as a trade chip, he'll be one of the better pieces out there. No one is going to be trading a top 20 pick from this year. The D+2 guys, you have a better idea of what they are and teams will want to keep the winners. The ELC could be valuable in future years if you hang onto him.
As an NHL projection, skating is a concern. I'm not sure he will be able to drive a line or carry a scoring line himself, but if you put him with skill players, he should be able to produce. Not too different from non-'22 Kadri. Smarter player but worse skater.
