Bill Belichick

The historic four-decade relationship between coaching legends Bill Belichick and Bill Parcells.

When NFL superstar Barry Sanders vanished at the height of his career, he left the NFL world in shock. He was still in his prime, chasing the all-time NFL rushing record when he boarded a flight to England and never stepped foot on the field again. Now, 24 years later, Barry retraces his steps through the streets of London to finally confront the mystery.

The Bills went to four straight Super Bowls from 1990-1993. They're remembered for losing all four.
