If skating balance is a bit of an issue, that is coachable and can be worked on.
If hockey smarts is an issue, a bit of a problem. Coaching can improve it but the game is at an almost instinct level.
All of the above depend on how willing and coachable the player is.
I still put Guhle way in front on NHL level but after the juniors, not as high as I use to have him. Top 4 but maybe not so sure as top 2. We need all of our prospects to invade the AHL and then we can get a better idea of our defensive future.
