As I presented to you yesterday, the correlation between Super Bowl champions and first-team All-Pro performances from running backs is not one that is particularly strong. Out of the 52 Super Bowls that have been played to date, only 11 of them have featured a running back who was a first-team All-Pro in the year that their team won.
And no teams have won the Super Bowl while having a running back who was a first-team All-Pro since the 1999 St. Louis Rams, who also had a first-team All-Pro at both wide receiver and quarterback. But the running back did have tremendous success from 1985 up to that point, even with a lull prior to that and a barren wasteland since then.
