summary on the Leafs prospects from ESPN:
In one year, the Maple Leafs have quickly turned their pipeline around from mediocre to elite on the backs of trades and a strong 2015 draft class. The question I'd ask is: "Who doesn't believe in the little people?" because their system is very small, albeit dynamic.
Travis Dermott is a guy I wasn't too sold on heading into the draft, but after talking to a lot of hockey people about him in the following months -- and after a great under-20 camp for Canada -- I've been sold. He is a skilled two-way defenseman, but his value is tilted more toward offense. He rarely forces plays, and makes good outlets under pressure. He's slightly undersized, but does battle hard for pucks and shows fine defensive IQ.
Nikita Soshnikov will need some time in North America before he's ready to make an NHL impact, but he's toolsy, including above-average or better speed and puck skills, though he has work to do to round out his game.
Stuart Percy (11th) had an impressive start to this past season when he got a look up on the big club and showed fine. He's a very smart and safe defenseman who can make plays at both ends and has some skill. However, he's a pretty bland prospect in terms of upside and raw talent. Josh Leivo (12th) is a tough player for me to read. He's shown strong play at times during the past two years, getting a few NHL stints. He has size and above-average playmaking skills, quality all-around hockey sense, but there isn't a real "wow" factor to his game. He may be too bland to be an everyday NHLer, but he also has enough good tools to potentially get onto a third line.
The Leafs have above-average pipeline depth as well, with forwards like Nikita Korostelev, Dmytro Timashov and Carter Verhaeghe being young players with upside. I also liked the two-way play of defenseman Viktor Loov when I saw the Marlies play this past season.
Noteworthy prospect
Former first-round pick Frederik Gauthier has been somewhat stagnant as a prospect after being taken at No. 21 overall in 2013. He's big, and has improved his skating, with his mainstays being his great checking and faceoff abilities. I once envisioned a player with average offensive upside combined with high-end defensive skills when he was an under-18 player, but that reality is starting to look pretty unlikely, given his lack of development offensively during the past two years.
2015-16 impact
Both Mitch Marner and William Nylander will get looks at camp. If you'd asked me a few months ago, I'd have said I expected Marner to go down for a season to the OHL, but after how dominant he was at the Canadian under-20 camp -- where his strength seems to have gotten better -- he could be a candidate to stick. Nylander will be an NHL candidate too, and if not, he could spend about another half season in the AHL before a call-up. At some point, whether due to injuries or the selling of veteran assets, I think you can expect an insurgence of young players during the season between Nylander, Connor Brown, Scott Harrington, Percy, Leivo and others.
