I think we all agree KK is not NHL ready. Unfortunately, the AHL is not an option. Hence, we need to ask ourselves what is the best way to develop KK?
As long as KK is not overwhelmed, I believe the Hawks would like him in Chicago for 39 NHL games as well as practicing / training under their new staff. Hopefully, he also has the mental fortitude to handle the adversity (that would be huge). If not, he's going back to Seattle after the 9 game audition. Finally, KK will be playing in the World Juniors in the middle of the season regardless. If KK sticks around Chicago, he'll get about 50 games this season at 19 years old. That's a good number of games for his development while not starting his UFA clock.
