Throwing a receiver open isn't the issue... it may make the issue worse, but there are times when defenders just don't play a proper zone. For example, a last second hail mary and the deep zones let 3 WRs run right by them. Here are some examples of worst case scenarios that I saw this past week.
425 Alignment vs No Huddle
425 Cover 2 Sink vs Swing Pass
Bad deep coverage
CPU Shotgun Speed Option
Bad deep coverage #2
Hail Mary gets behind deep coverage
