Dont worry about it .. My goalie lately is the same ... avg 5-6 ... mybe the defense do a great job then goalie dont have to do anything ... just sit and watch infront of goal .. lol
Its not totally true in my case. My defense id strong and they do a good job but once or twice, when my opponent gets through that and shoots, my goalie never saves. Well I just bought a new one. Lets try him in the match!!!
