Who was the greatest college football team ever?

My vote is 1972 USC Trojans. They were so explosive and talented. Ourscoring teams like 40-6 avg. Alot of people say 1995 Nebraska but I think 1971 Nebraska would beat them. Don't answer with modern teams cuz teams more talented then, they had more schlorships. 2010 Auburn not even in top 50 all time. You have to consider 1961 Alabama, they gave up 25 points all season in 11 games. That's 2 points a game average. Awesome. Alot of great teams like 1968 Ohio St and 1969 Texas. 1976 Pittsburgh with Tony Dorsett. I wish they could have real life All Time Tournament.
