I'm on a Vikings history binge. We all like to think that Adrian Peterson is a violent runner, and he is, but the Vikings also once had Bill "Boom Boom" Brown carrying the rock. This guy was mean, tough and unrelenting. Peterson is a better running back with out question, because he has many things Brown did not. But for old school, smash mouth football, Brown would be my man. Obviously all I have to go from is old video, but this guy was always tattered, bleeding and smiling! With the new rules in the NFL, and the players all but required to wear skirts out on the field, it's therapeutic to watch old film from when we proudly played in the black and blue division.
