As a youngster myself, I'm an avid fan of the Ontario Hockey League. Here's a little run through of the "kids" that once dominated that league who have since been drafted up to the NHL that you should look out for:
Yakupov for the Oilers had an awesome rookie year, but such is to be expected from the #1 draft pick in 2012!
Alex Galchenyuk was really awesome for the Habs last season. I remember in my Eastside Hockey Manager game (that had been patched and updated) I used to always have him in my OHL team until he got too old to play in the league! He'll be a star player by 2017 I reckon.
I'm really excited to see if Nathan MacKinnon, who was the first overall draft pick this year, gets much ice time with Colorado. I've only seen a few videos of him on Youtube and he seems pretty decent, but then again, everyone looks pretty good when you're watching their highlight reel... But he's reported to be the next Sydney Crosby, though I think part of that is because he's from Nova Scotia.
I'm expecting a decent season from Ryan Strome. He was a top player in the OHL with Niagra for like three years, but I didn't catch much of him last season with the Islanders' AHL affiliate (simply because I couldn't give a shit about the AHL). I absolutely love how skillful he is. The up and coming Cristiano Ronaldo of ice hockey.
There's also a few pretty decent keepers coming up. One in particular for the Belleville Bulls in the Ontario Hockey League called Malcom Subban could turn out to be a big name in the future. The Mississauga Steeleheads keeper Spencer Martin looks like he'll also have a bright future ahead of him.
