Following another edition of the IIHF World Junior Championship, it's time for an update to my ranking of the top drafted NHL prospects. Of the top 50 listed below, I have seen 47 live in action during the past six months, and 49 of 50 overall.

The 2014 NHL draft looks pretty solid so far about six months after the selections were made. After No. 1 overall pick Aaron Ekblad, there doesn't seem to be a clear "elite" type of prospect -- unlike the presence of several at the top of the 2015 class -- but the bulk of the first round looks very strong, including an impressive European class. As of now, the prospects that were eligible to rank here formed a five-man tier at the top.

A lot also changes in six months. For one, around 20 of my top 50 prospects in my summer update have graduated to the NHL. Players can also significantly shift in that time span as well, thanks to jumps they make (or fail to make) in their development.

Prospects are considered "graduated" if they have more than 25 games played this season in the NHL, 50 career NHL games, or are currently on an NHL roster. Thus, players like Mikhail Grigorenko and David Pastrnak are considered graduates.

Here are the top 50 NHL prospects:
