Wow, I couldn't disagree with this statement more.
Women's college hockey 20 years ago was unwatchable; 10 years ago it was tolerable; today it is great. The improvement in the last two decades has been equivalent to the improvement in men's college hockey in the 20 years between say 1955 and 1975. Different programs rise and fall but the overall quality of the game improves every year, and the improvement seems to be accelerating. Women's hockey now is better than women's hockey 15 years ago by an even greater amount than women's hockey in 1998 was to women's hockey in 1983, which itself was significant.
I think this is a confusion between the dominance of programs in the early days of a sport when the meager talent is highly concentrated, and the diffusion of much greater talent among far more teams as the sport reaches maturity. It used to be there were a dozen forwards in women's hockey who could skate through entire defenses. That's not because those women were great -- it's because the defenders were horrible. The bottom has risen so fast in the game that it has taken a chunk out of the top -- that's what happens in every sport when it becomes serious.
