Blue is offence, Red defence. For simplicity, suppose this is right off a pull that went OB. This is a common first set up, and highlights why break throws are death to defence. Red is forcing flick, defending the top endzone.
Red 1 (the mark) bites too hard on a fake by Blue 1. A backhand break is demonstrated here - an inside-out flick is possible as well and just as deadly.
Because R1 is out of position on the mark, an *EASY* backhand break throw is let out
R4 is out of position because they had been on the open side of B4. This results in an easy play for B4 on a continuation break.
NOTES: R7 was beat deep, and R4 was broken as well. However, none of this happens if R1 holds the force.
