Why is it not reasonable? If a guy is showing to be behind in certain root issues in playing hockey, why is it unreasonable to keep him in leagues to work on his game until he's met levels to show he's ready before he's thrusted into a league he's not ready for?
Where did I say he needed to be in development for 5-6 years? IF it takes that long to develop him, then so be it. Guy is 20 years old. To act like asking him to be developed in a logical manner, when your organization has the time to do so, and can structure the team to allow him to do so, is somehow unreasonable, is quite weird.
We have a ton of examples of players that were developed terribly, while seeing the organization continue to rush players to the NHL roster, and thrusted into roles they are not ready for the exact same ways and decisions in deciding WHERE to develop players. Nothing has changed with this organization. They aren't patient with their prospects.
