I am Jack O'Brien. I started playing football in a local league in the 3rd grade. I didn't start taking it seriously or try to get better until 7th grade junior high football. In my 9th grade year I played varsity special teams on kickoff. I also ran track that year to help improve my speed for my sophomore year. I started the year on all special teams but ended the season playing positions everywhere on the field. I started varsity on the 4th game of the season playing middle linebacker. from there I played d-line and some full back.
