I post it before I forget it
I was thinking of uniforms. I believe, since the best way is to play iron squad (at least to begin the system and see how it's working), the risk is to have teams with same (more or less) colors. Since we play on video, we NEED a method to easily see the 2 teams.
So I thought about a really easy way. Painting the plateform (grass or plain plastic) with diferent colors.
We just have to create a color chart (see example attached file) and each team engaged will have to paint the plateform to the color they depand.
With that, the game will be easy to follow on the video, if the light is good enough.
The major advantage of that technic : you can play any team you want. You can invent it, use college, pro, european, japanese, etc... we'll be able to see 4 teams of Niners, 2 teams of steelers, etc, etc... No problem of color, away or home usual stuff.
