Fleury is a big-bodied rearguard with offensive skills. He will occasionally take risks, as he is a very confident rusher of the puck. He can be physical when the need arises and is capable of handling bigger forwards in the defensive zone. Not flashy or offensively-gifted, Fleury is a sound, consistent defender with the ideal size and technical skills to be a shutdown player at the pro level.
Fleury attended Hockey Canada's training camp for the 2015 World Juniors in August and his first training camp with the Hurricanes before returning to Red Deer for the 2014-15 season. Fleury competed for Team WHL in the Subway Series and is expected to be in Canada's lineup at the WJC as an 18-year-old. While opinions vary widely amongst scouts about his long-term potential, the Carolina personnel staff feel he can one day be a Jay Bouwmeester-type defenseman capable of playing big minutes and controlling the game in his own end.
