Forcing forehand. Set up with man defense on handlers and zone defense on cutters. D1-3 are burners, D4 and D6 are wings, D5 is short deep, D7 is deep deep. D4-6 should shade towards guarding the force side cutters and leave the breakside cutter, D4, relatively open.
If the disc is swung between the handlers, the burners can stay in their positions.
If one of the handlers cuts up line, such as O2, D2 guards the upline cut.
If O2 continues upfield, D2 releases him to D4 and then searches for another handler to guard.
If O7 in this case comes back to handle, D2 picks him up.
If one of the cutters receives the disc.
One of the burners gets on the mark while the other burners shift to guard the closest handlers.
If the cutter dumps the disc.
The mark, D3, finds the next handler to guard.
One of the vulnerable areas in the clam is a quick pass back to a cutter after they've dumped it and before one of the downfield defenders can cover them.
The downfield defenders have to move quickly to stop continue throws while the burners move into position.
Another way to beat the clam is for one of the cutters to come down as a fourth handler and then try to get open.
For example.
There is another vulnerability.
Which is the hammer over the defense to one of the cutters.
The important thing once again is for the downfield defenders to shut down the continue cuts and let the burners get on the mark. The breakside wing should be ready to contest the hammer.
