handler 1 swings to 2, the cup needs to respond with marker 1 marking handler 2, and the rest of the cup shifts accordingly.
handler 2 looks to swing to 3, when he does, marker 4 must not bite on it or try to set a mark...
marker 4 has to get to the sideline as the disc is swung to 3, rather than biting on a swing he has no chance of getting and allowing the swing to 4 to turn into an easy up field look.
Now when the disc gets to handler 4, the mark will be there simultaneously or shortly after, preventing the up field throw from going off.
handler 4 wets himself and throws something floaty that gets pushed back by wind, the entire cup simultaneously gets a callahan.
