Zaitsev, 24, signed a one-year contract with the Maple Leafs after spending the past seven seasons in the Kontinental Hockey League. Zaitsev also played for Russia at the World Cup, finishing with two assists and a plus-3 rating in four games. He showed he can keep up with some of the best talent in the NHL, but can he do it over the course of an 82-game season? Zaitsev's career-high in games in a KHL season is 57, and he'll have to adjust to the grind, the skill level and the smaller NHL ice surface.
