Standard Zone O Setup: 3 handlers, 3 mids, 1 deep.
Alternate Zone O Setup: 2 handlers, 2 wings, 2 poppers, 1 deep.
Blue 1 & 2 are the primary handlers. They maintain their position within the middle of the field. Typically, they provide an option for a dump or break force throw.
Blue 3 & 4 can fill in as a far side handler on the wing.
Blue 1 now has a swing pass to 3 as an option.
But that pass may be taken away by the Zone D, or the handler might also want to exploit the weak side.
Blue 1 also has 2 as a dump / break pass option.
As the disc moves past the mark (Red 1), there is a window of opportunity to make a swing pass to Blue 4 who should time a cut to gain yards.
Once the disc goes up field, Blue 5 and 6 should be looking for continuation cuts.
Blue 6 reads off of 5 and looks for another continuation pass.
If no continuation exists, reset to a handler.
