Looking back on those games, I probably hustled out of position as much as I hustled into position since I really never had any real training. I was working on instincts alone.
I do it as a therapy. I do it as something to keep me alive. We all need a little discipline. Exercise is my discipline.
If I stay alert, then I can challenge myself, and by challenging myself, that helps me to stay alive and to hopefully take something away from the experience.
