Came across this interesting obituary about one of the pre- SB Jets, Sherman Plunkett, a huge man in an era of 240 lb. DL. Includes some Johnny Sample quotes since they were college teammates. http://www.nytimes.com/1989/11/24/sports/sports-of-the-times-the-day-plunkett-took-it-easy.html
That was the era before college sports went professional. Nobody takes it easy on the opponent in the pros and at least a quarter of the college football programs are professional in all but the wages they pay their players.
