Handler (1b) starts on the 'Off side', the opposite side of the pitch to where theyre being forced. It is likely that as a break throw would be so likely to score from here, the defensive will likely set up with at least one defender poaching on the break side. Obviously, if there are no poaches, a break throw here would be a high quality scoring option.
Assuming there are poaches, a dump into the middle of the pitch to (2b) opens up a range of opportunities. (1b) recognises that there is a lot of space to attack on the open side. So sets up an upline cut as soon as they have thrown. (7r) is likely to be slow to react after (1b) has thrown the disc, so the upline cut is likely to uncontested if (1b) times their movement well.
(1b) cuts up the line uncontested, and receives the score.
Alternatively, (1b)'s upline cut isn't good enough, and (2b) doesn't throw the disc. Unlike in the 'on side' play, the coathanger style cut is not productive in creating a goal scoring opportunity as (2b) is so far away from the 'on side' that (1b)'s cut would have to be incredibly flat to hit the line, leaving not enough space to cut back across into. (If the set play is started further across towards the 'on side', then the 'cut back' or coathanger style cut is a scoring opportunity). In this case, (3b) has pulled their defender, (5r) across.
Cutting straight towards the open side laterally, (3b) can put (5r) on the back foot, and get past them for the score.
Alternately,
(5r) effectively protects the open side, and this opens up the option of a break throw.
(2b) can throw almost any break throw here, as the whole of the break side is free. We can't predict the defense's shape or positioning, so there may be poaches in the lane. If this is the case, (2b) should be able to view the play and react accordingly. If none of these options are viable throws given the conditions, the 2 options given shouldn't have taken more than 6 seconds of a stall if done fluidly. A reset may be required, and appropriate play from there.
