You can have too many defenseman, too many centermen, you can have not enough wingers,” Regier said. “You can have a situation where it’s difficult to decide between two goaltenders, one from each organization… It puts a lot of strain on the coaching staff, it puts a strain on the development process. While it can work… it is much more difficult than having your own organization.”’
