There are a few things you need to have ready before beginning the recruiting process:
Combine your best offensive and defensive plays together into one video (about 3 minutes long).
Full Game Footage
Full game footage needs to be accessible. After viewing highlights, college coaches will ask to watch your full games.
List a few subjects/majors you are interested in studying.
Location & Level
Think about specific locations where you would consider attending college. Examine, realistically, what division you are capable of playing at.
