I would say based on what has happened these last few years that I edge closer to 417s side of the development debate, but I have a lot more caveats on this. The issue isn't particularly with developing in the NHL, it would be allowing the space and having the people in place to allow it to happen.
The Bergevin regime development couldn't happen in the NHL and very rarely happened anywhere else, they didn't have the resources, they didn't see the value in it, and they didn't create an environment ripe with the right type of teachers for it to happen.
So I am less concerned about players being brought up too early because development is something this new regime believes can happen in the NHL where the previous regime were all about results and didn't care about tomorrow.
