i think one way to boost people to get supporter is this
get a scouting report, clearly see what to expect from his next opponent
1. highlight new comer to opponents team
2. stats meaning we should see +5 or -5 if certain players play or not.
3. opponent team strategy are studied meaning if the run look inside what are the % they win and why
4. if they lose its because of who or what strategy
5. breakdown of your team going against them
im still thinking what to add more, this are the things i do when i scout my coming games.
