I hate how a rookie can play in the NHL but not in the AHL until he's 20 (?). With marner I think he could benefit from staying in the OHL next year but I really wish we could put in on the marlies instead, even if only in the beginning to see if he can elevate his play to that level. A challenge like that, getting their feet wet, could be very beneficial to some players.
Some aren't ready for the NHL but have nothing new to learn in junior, its a shame they have to be stuck in one or the other
I have put a lot of thought into the CHL-NHL agreement, and honestly, I think its for the better. By that I mean, there will be players who are hurt by the system, but ultimately it protects a lot more.
The advantage of the system is it prevents many prospects who are talented, but need development time from being rushed into pro hockey in the American league when they might not be ready, just because they put up big junior numbers. A prevalent example I can think of would be Michael Dal Colle. If Dal Colle was AHL eligible, he probably would have started the year there. But considering his start with Oshawa, my guess is he wouldnt have lasted there long. Probably would spend some time in the press-box before being sent back to Oshawa, so he ends up in the same place, but his confidence is likely even lower.
Another type of player who could be hurt are the smallish types. Lets say a Brayden Point. Brayden Point could be a candidate for the AHL this year, but long-term its probably best he dominates junior. If the AHL was an option, the player (and his agent) would probably push for that, because its another option + they would get paid + all the other stuff you dont consider, like not needing a billet family etc.
Lastly, when you send a prospect back to the CHL, you let them develop but not having the temptation of the NHL as an option. Look at the fact that some of us are clamouring for Nylander to be called up -- thankfully the Leafs are ruling it out, but other organizations would heed that temptation, especially if injuries take hold. Now I know Nylander can probably handle the AHL, but Kasperi Kapanen cant.
The main players who suffer in this system are the tweeners -- the Brayden Schenns, the Jonathan Drouins etc. In the end though, they generally end up where they should be
