In juniors, Gaucher was a something of a jack-of-all-trades. At times, he played in an offensive role alongside Quebec's most gifted scorers and showed his ability to complement their games, tallying 46 points in 44 QMJHL games. Other times, he slotted in the middle as a shutdown center, tasked by Roy to eliminate opposing top lines. He did that well, too, with a league-wide award to prove it.
