Rules Analysis
Disc space:
Merely running means running for the exclusive purpose of reaching the other side. Running with an ulterior motive of interfering with the thrower in any way is not "merely running" and is a double team.
Straddle: If a line between the marker's feet is less than one disc diameter away from the pivot of the thrower, it is a straddle violation.
Wrapping: If a line between the marker's hands is less than one disc diameter away from the torso or pivot of the thrower, it is a wrapping violation.
However, if any of the above situations are caused solely by movement of the thrower, it is not a violation.
The thrower may choose to call "disc space" for both straddle and wrapping violations as they are a subset of disc space violations. However, the thrower may also choose to call the more specific violation for clearer communication to the marker about what needs to be corrected.
