As for my rebuilding roster, despite having several young talented players I feel there is no point listing 30+ names considering that only 23 would be on a roster at any given time, so here is my best constructed prospect roster:
Max Domi - Nathan Mackinnon - Sebastian Collberg
Sven Baerstchi - Aleksander Barkov - Alex Chiasson
Emerson Etem - Teuvo Teravainen - Tom Wilson
Brett Ritchie - Henrik Samuelsson - Ryan Hartman
Extra: Adrian Kempe
Griffin Reinhart - Jacob Trouba
Josh Morrissey - Madison Bowey (WJHC 2nd pairing)
Shea Theodore - Matthew Dumba
Extra: Chris Bigras - Adam Larsson
Petr Mrazek
Robin Lehner
Thats a lot of depth in the most important positions in the NHL. Mac, Barkov, and TT are excellent prospects at C, 6 first round picks including 5 within the Top 13 picks for Defensemen, and 2 of the best young goaltenders in the world.
Not to mention, so many players have a winning pedigree. Domi, Morrissey, Bowey, and Theodore won the WJHC this year, TT won last year, Trouba and Hartman the year before that.
Brett Ritchie was a part of the Texas Stars AHL championship last season, Mrazeks Griffins won the years before Ritchie, and Lehner won it as a 20-year old only a few years ago.
Mackinnon won the Memorial Cup 2 years ago.
Adam Larsson in his short NHL career has already been to the Stanley Cup Finals.
Lastly, Hartman and Kempe were drafted by teams with recent winning traditions. that is not to say they are winners but if great teams like what they bring then so do we.
