Czarnik is a talented offensive player who still has a lot of room to develop as a hockey player. He has good vision on the ice, a solid shot, and a developing two-way game.
Czarnik has developed slower than anticipated and he has seen his playing time and production decrease significantly. 2013-14 should be considered a statement year. With younger forwards coming into the system, Czarnik will have to prove he is worth keeping around.
Czarnik was dealt by the Los Angeles Kings to the Montreal Canadiens in exchange for Steve Quailer in February of 2014.
