Kerdiles is a forward prospect with good size and maturity beyond his years. He projects more as a two-way forward than a purely offensive prospect, but he does have some puckhandling skill. Kerdiles has a good motor and is not afraid to take the body when the opportunity presents itself. He is not a flashy player but is instead a player that relies on his smarts and effort to make things happen on the ice.
After posting just over a point-per-game in his freshman season, Kerdiles will return to University of Wisconsin for his sophomore season in 2013-14.
