These are a few rules that are often misunderstood and important under somewhat common circumstances.
A stall count can only be started when the marker is within 3 meters of the thrower.
On a pick or any other foul, if the disc is in the air, the pass must be completed otherwise the result is a turnover. The same holds if the disc is thrown after a foul or pick is called. Thus, if team A throws the disc and a pick is called, play continues until the disc is caught. If team A fails to catch the disc, it is a turnover and the foul/pick is ignored. Otherwise, the disc is returned to the thrower and the foul or pick is resolved.
Please yell picks and fouls loud enough so that all can hear.
