Realizing that my last post probably sent Juulie back over the edge, I'll try to save her.
The only plays that are going to cause you to actually think are:
A loose ball and fouls by team A near the point where team B gains control. Solution, did B have the ball before the foul? If you answer no, TC foul.
Fouls during rebounding after a player on team A secures the rebound, not during tapping. Solution, did A1 have the ball before the foul? If you answer yes, TC foul.
Fouls away from the ball near the time of release of the shot. Solution, was the try released before the foul? If you or your partner(s) answer no, TC foul.
Hope that helps.
