Very reasonable and level headed part here. This is kind of how I see it playing out myself. More players in the 16-18 yr ages in the league, with some of them then leaving at 18-19+ if they are good enough.
Also think that there will be a weird issue if college teams perhaps "overstock" their rosters, creating ice time issues as well. With that in mind, I wonder if the CHL becomes a weird de-commit option for players mid season before entering the transfer portal?
Yeah I think you'll see a lot more of those kids like Makar, Powers, Johnson, Fantilli, etc. who otherwise stayed out of the CHL to maintain their NCAA eligibility who will now be more than happy to stay in Canada and play in their respective CHL leagues while having the option open to go to the NCAA for their draft year or post-draft.
The other interesting development which I just thought of is the AHL. If you are drafted out of a CHL league you cannot play in the AHL until your 20 year old season. The same is not true for NCAA kids, who if they sign, can play AHL right away.
I'll use Gavin McKenna as an example. It's likely that if he does go to the NCAA next season for his draft year he will be a 1 and done and sign for the 26/27 season. But it gives his draft team an option to send him down to the AHL in his D+1, an option that wouldn't exist if he was drafted out of Medicine Hat. This will have much bigger impact for more physically developed players that have outgrown CHL competition. Go play CHL at 15, 16, 17. Jump to NCAA in your draft year at 18, sign the next season and go play AHL at 19 a full year earlier than you otherwise would have been able too.
It begs the question of if CHL teams are already going to be losing a lot of 18/19 year olds to the NCAA, should they just do away with this rule anyways and let teams and players decide where is best for them to play? Let the full gamet of options be open to players and teams to best decide. Do they sign an NHL contract for a chance to play in the NHL, get sent to the AHL if not ready, or get sent back to the CHL if not ready there or remain unsigned and go play NCAA?
