In 2017, football analytics savant Aaron Schatz put on his historian hat for an interesting piece in ESPN. The creator of metrics like DVOA and DYAR went back into the archives to find players who had “hidden Super Bowl rings,” a term he coined to describe when a player is on a title-winning team for a brief, forgettable period in their careers.
Schatz’ prime example is Bernie Kosar, the long-time Cleveland Browns quarterback. Kosar had a falling-out with Browns head coach Bill Belichick and landed with the Dallas Cowboys midway through the 1993 campaign.
