It would come at a price of course. Additional compensation would be key.
part of the problem with trying to change that deal is that you are often looking at the exception for the player that should be able to move up....the majority of the prospects need to be there for the 2 years and the nhl is relying on those teams to develop players for them.
there are exceptions when its not perfect but overall the relationship works pretty well
changes are called for, the landscape has change, due to many factors, including the immediate impact of some younger players, the greater readiness of more younger players, and the improvements in scouting, and on and on
one change i think should be considered, not just re CHL but re the Entry Draft,
is limiting 1st-year eligible players to only be available thru the 4th, or maybe 5th round.
These days, a kid who showed a scout 1 good game, might be deemed worth reeling in with a late pick gamble
This would force team to make some tougher choices, and maybe get more qualified kids drafted.
I think any resistance would fade quickly
