100% of 3 Pros
If you don't make it on the field remember there are numerous careers that are tied to professional sports from marketing, being an agent, an athletic trainer, data analyst, or broadcaster!
NFL may be your dream but you can do what you do best on high school or college teams. Doing great work on these may land you a job in professional teams (NFL, NBA, MBL).
All of these are great options. Work hard and practice like you play the game. Remember though that less than 1% of young athletes make it to being a professional athlete. Always have a back up plan. Good luck
