I have read a few posts and understand that you have comprehension issues.Hey Joe - l think many would disagree that Hird was responsible for the program.
Hird was the coach and therefor in charge of everything designed to maximise the on field performance. He hired people with the intention of maximising the on field performance.
Those hired clearly adopted a program that has resulted in this entire saga and Hird either knew directly, or was negligent in not knowing.
The ultimate responsibility for the program lies with the person, who facilitated its introduction. That person was Hird.
