Randomly watching the NHL throughout the year, they really seem to be emphasizing "american" stuff...heres a chart of the top american players on the team. Heres' the American stop players for todays game. And they seem to make a conscious effort to point out the US colleges these players attend.
Has it always been this way or has this amount of stuff increased in recent years in response to something (a shift in better US players, a need to connect the game to the US viewer more)?
