I’ve seen three options ...
1) Play Legion for a lighter schedule and focus on physical development
2) Play 20u to play with younger, typically D3 players and other incoming freshmen
3) Play in a collegiate league that allows incoming freshmen
Even though my son returned from his injuries in time for senior year he still needed rehab to get college ball strong again. He went with #1. All the seniors returned from travel to play Legion for one last hurrah. The team went to states for the first time in years.
A (now years later) humorous moment. My son and several teammates returned from the Shore for an 11am Sunday morning game. It was Senior Week at the Shore. I arrived first. When the kids got out of the car my first question was, “Did you get any sleep?” The response was five kids laughing. They slept for three hours. My second question, more importantly, “Are you all sober?”
