Playing at home always gives the sporting team an edge. The crowd noise, the chants, celebrations, heckling, etc. Players get that extra adrenaline and use it to their advantage, giving them a little extra boost to their game. Obviously, elite players such as Crosby and Ovechkin will dominate no matter where they play, whether that be at home or away.
The tricky part to dominating your fantasy hockey league is finding those pieces of gold that consistently put up numbers just as good on the road, as they do on home ice.
