It is a team sport. Having a stud (at any one position) will not help you win anything if the rest of the team is weak. If you have a team filled with good players then a great player or two will put you over the top. It can be a super star goalie, a dominant fogo, a stud defender it really doesn't matter. Insert a stud into a team of solid players and it puts the team over the top. I think a team can be competitive without a solid goalie but it certainly helps to have an above average guy between the pipes.
