Gonna knee jerk here but maybe it was actually Cole that made Jack better.
I’m not going to go dig the posts up, but a lot of folks, including scouts, suggested his numbers were boosted playing with Jack.
Not suggesting it was the other way around but if anything, early indicators say Cole will be just fine.
At the NHL level, if he is paired with Kotkaniemi or Poehling, I think the size issues will be mitigated somewhat. Ideally, there will be at least semi skilled power winger with them.
