Millers age is based on the age level a player will play at during the Summer season. As soon as the Summer season is over, we start focusing on the next year (#YourNextLevel). For example, starting in August, if a player will be playing 12U the next Summer, they will play 12U Millers for Fall through the following summer.
Once a player completes their 14U Summer season, they are considered Freshmen and 15U eligible. We want players to understand the rigors and expectations of playing at the Varsity level so getting players up that learning curve is critical to their development, exposure and performance.
