Y'know, it's funny...the assertion from the club side is that the success or failure of high school teams is directly related to club training or lack thereof--to the point that no high school team can be successful without the question, "where do their players play club ball?"--unless they are dissatisfied with the clubs, in which case they are two entirely different and independent issues.
Sometimes, in the case of high schools, it may be that a PARTIAL factor is the CONCENTRATION of upper-tier club players that are members of a single high school's team, as opposed to when a club team's members, in the spring season, are more scattered throughout multiple high school teams. Just a thought.
