Unless ML lost the head coach, then I doubt it will be a problem. But NL will be tough to beat.
Reality is that when a team loads up, quality players get less playing time and start to cycle out because, after all, what's the point of this racket if your son isn't getting run or, for example, relegated to defensive middie when he has offensive aspirations? If a club director is focused solely on winning 6th grade HoCo, then that will come at the expense of player development. Although quite talented, ML has consistently won, not necessarily because they have superior talent, but because they have retained quality players that know the offense. The star today is unlikely to be the star in 8th grade, so best parents can do is make sure that their boy's club offers a healthy balance of competitive play and opportunity.
