Try Outs
At Colorado Boom, tryouts are more than just an evaluation—they are the beginning of your journey toward excellence. We are looking for dedicated athletes who possess a "team-first" mentality, a high "Volleyball IQ," and a relentless work ethic. Our tryout process is designed to be fair, transparent, and comprehensive, ensuring every player has the opportunity to showcase their skills in front of our entire coaching staff.
What to Expect
Our tryouts mirror the high-tempo environments found at national-level clubs like Elevation and Front Range. Athletes will be evaluated on:
Technical Proficiency: Mastery of fundamentals (passing, setting, hitting, and serving).
Court Awareness: Ability to read the game, communicate effectively, and transition during play.
Coachability: How well an athlete takes feedback and applies it in real-time.
Athleticism: Agility, verticality, and explosive movement.
The Evaluation Process
Skills Assessment: Positional drills to gauge individual technical ceilings.
Game Simulation: Scrimmages and wash drills to see how players perform under pressure and within a team dynamic.
Placement: Following the session, our directors and lead coaches meet to finalize rosters. Colorado Boom follows all RMR (Rocky Mountain Region) guidelines regarding offers and commitment deadlines.
Important Note for Parents
Selection is based on a combination of skill level, positional needs for specific teams, and the athlete’s potential for growth. We pride ourselves on clear communication; regardless of the outcome, our goal is to provide a professional experience that helps every athlete understand their current standing and future potential in the sport.
