Gauthier. This is about 2nd best prospect right now.
6'5, finalist for defensive player of the year in the Q in his first season, understands the physics of the game very well, active stick, relentless on the PK and underrated offensive ability (fatigue contributing at the end of the season leading to 8 points in 18 games, IIRC). His defensive ability is outstanding and indicative of, at the very least, a very good shutdown center. I foresee him as a very good 55-65 point Bergeron/J. Staal/Zajac-type center
It's close between him and Colborne right now, if you ask me. Big Joe has more pro experience and is closer to the NHL but Gauther is much further along than Colborne was at his age.
