Seguin, Subban, Bobrobski (spelling wrong I know, but the Philly goalie) basically EVERY rookie will make an impact on his team.
The size of the impact, and if it's positive or negative is the real question.
But I think the three I mentioned all will have a fairly large and positive impact for their teams.
@ AKA miles.....so an american born player being the captain of the Habs has zero impact?
