The following pages included page with court boxes for their defensive sets, zone, man, match-up, special defenses, and presses. This keeps your notes organized and uses a system which can be easily located and filed. Over a period of several years I always kept a folder with scouting reports and game reports for each team we played or will play. This leaves you time during the game to concentrate more on team tactics and strategies. This means every player get's some comments.
Coaches probably approach their scouting reports in a variety of ways.
The more experience you have, and the more familiar you are with your opponent the easier this becomes. It is also important to get half-time and post game stats from the host team. Most schools will cooperate if you are polite and introduce yourself. Finally, during the game try to keep a good eye on their substitution patterns. Which players come in at what times, and how that affects their offenses and defenses.
