One thing to consider in this mix, is that some players do not play their club position in high school when you talk about perhaps some players not "shining". They play were they are needed due to their skill level. If we put some NW players out of their "normal" position and put them on center defense, could they play it well, yes, but could they play it as well as perhaps those who play it year round?
NW was fortunate enough to have 8 players that play together almost 12 months a year for over 5 years now. They know where to move to space, where to receive the ball and and generally sense how plays are developing. That is a hard thing to teach to 22 HS players who come together in January and break up in May and play at different age and skill levels.
