Gauthier was drafted by the Sabres in 2010 after putting up big offensive numbers in junior hockey. Displaying outstanding skating ability and offensive vision, it was hoped that despite his lack of size and awareness in his own end he would eventually be able to overcome those liabilities. Now in his third pro season, he has worked to improve his defensive game but has yet to show the offensive explosiveness of his junior days.
Gauthier-Leduc signed a one-year contract with the Sabres in July 2015 and began the 2015-16 season with Buffalo AHL affiliate Rochester. He was dealt by the Buffalo Sabres along with Phil Varone and Jason Akeson to the Ottawa Senators in exchange for Cole Schneider, Eric O'Dell, Michael Sdao, and Alex Guptill. Now in his fourth pro season, the 23-year-old has never put up the type of offensive numbers he did in junior hockey but his size and mobility suggest he has some lower line potential.
