I can tell you the answer is a resounding yes. We recently had Taylor Cummings at our clinic and it is well chronicled that she started in MD playing Club for a B Team and most consider her the best woman's player ever. Some of the best players on our club at the older ages worked through our club and developed their games playing B. Lot of these kids don't get their growth spurt to later. Conversely some of our "stud" players now struggle as kids have caught up to them in both their skills and physical assets. Look carefully for the players that have vision, hustle, heart, dedication, and may be undersized alot of them flourish later in middle school and high school. We also have kids that transition into lacrosse from other sports a little later and don't have the stick skills as much as a child starting at 4/5 yrs of age.
