It's being pompous to state that YJ is not a well coached team? Do you really disagree?
Maybe it's more than just team coaching coaching. From watching this team a few years, it seems that each year we play them they struggle with the draw. As a matter of fact I have yet to see a LI team at this age who has a half-way decent draw girl or game.
As far as this team goes, it seems that they were all exceptionally advanced athletes that the other girls are now just catching up to. They always played a very fast athletic game, with little strategy. Now that they other teams have girls who are beginning to equal them and catch up athletically this area of advantage has become more level. You will see other teams passing them in the coming year as well.
