Above the line
Event + response = outcome. A tough call, a benching and a loss are all events. Each coach and player owns his response, and the response shapes what happens next.
Oak Park's reputation for academic excellence translates to the field with the coaches' focus on developing players' game IQ and decision making. Skill matters. It is coached at every practice. Physical strength and speed matter. Investments of time in the weight room or working on speed can pay big dividends on the field. But the coaches believe that in winning vs the most challenging opponents, the critical difference is mental toughness, communication, and game IQ.
- Real development
- A dedicated Head of Player Development brings D1 college champion level skill work to every practice. Coach Sam makes time for team drills and for focused, 1:1 development in the areas of greatest opportunity for each player.
- A growing program
- Oak Park boys lacrosse closely supports the United Youth Lacrosse program. Oak Park high school players coach United K-8 recreational league players and model ideal sportsmanship, work ethic, and teamwork standards.
- Brotherhood
- Team dinners, bonding days, charitable work and awards programs forge strong connections outside the stadium.
