World class anything is difficult. And if you've never seen it up close, then you will have a hard time understanding the price you have to pay to achieve that status.
IMO, HCBK has put together a coaching staff which has seen what championship caliber play looks like. They know what they're trying to achieve and what they are looking for in the boys.
If the last half of the season is any indication of things to come, I think we are about to witness the difference between style and substance. Year 1.5 is gonna surprise a few folks.
