The 1972 Miami Dolphins made history as the only team to ever go undefeated and win the Super Bowl in a single season.
Forty five years later, key members of the legendary squad are now paying a dear price for their sacrifice.
At least seven players from that team either have suffered or are currently suffering from cognitive disease that experts believe were caused by repeated head trauma suffered during their days on the gridiron, according to the Miami Herald.
Earlier this week, Sports Illustrated profiled the decline of the Dolphins' rugged captain, Nick Buoniconti.
The 76-year-old former middle linebacker for the Dolphins and Patriots was diagnosed with dementia in October 2016.
