We went back to 1970, the year of the AFL-NFL merger, to find out. We counted players who appeared in each Super Bowl since (players who were on the roster but not active for the Super Bowl were not included). We counted each player only once (Tom Brady counts as 1 in Michigan's total, Joe Montana counts as 1 in Notre Dame's total, etc.). We also have included players from the Patriots' and Falcons' 53-man rosters who have not yet played in a Super Bowl to the count.
