If there's an argument to be made to separate the forward positions in hockey for fantasy roster construction, the crux of that argument is made around the validity of the center position to stand on its own.
I'm not saying there is a good argument to be made; my stance is clear from previous positional previews that the best fantasy world is an all "F" forward fantasy world.
But I get it when it comes to centers. They are the position from which an offense is built. They are the foundation for roster construction in the NHL.
