Reggie Jackson mentions in his book,Sixty Feet, Six Inches, how he operates under pressure:
When there’s pressure, usually, there’s also an unusual amount of attention from the outside. Everyone in the park–and sometimes, everyone in the country–is watching. That was a good scenario for me. I like that. I needed that. It helped me focus.
I called those Reggie Moments.
So Reggie needed the whole world looking at him to focus. I wonder what he could have produced over his career if he was focused all the time while playing.
