When my family first got a TV, the NY Giants games were the ones mostly on TV, so I became a Giant fan. I remember the games with the Cleveland Browns and the greatest NFL back, Jim Brown (who once scored 6 touchdowns against my alma mater, setting a record that lasted for 40+ years, and he didn't just score TD's, he kicked the extra points as well).
When I got to college, I worked in a dorm kitchen along with a man from Long Island. At that time lacrosse was very much a niche sport; I think it was popular on Long Island and upstate NY where Native Americans continued to play. As good as Jim Brown was at football, he was better at lacrosse, as John told me at the time and was ratified by the lacrosse people.
