There is a big difference between 7th grade lacrosse and what you will see in high school particularly the recruiting years in terms of lax IQ, size, and speed. The high school teams especially M&D and SW are constantly evolving until Junior year. Also, a few players from outside of MD typically flock to M&D and SW. In addition, many of these 7th graders will lose interest because of burn out and/or other typical highs school distractions like boys etc..... enjoy the grade school years while you can. |
