Johnson got emotional upon learning he will be enshrined in Canton as part of the 2020 class:
As part of the NFL's 100th-anniversary celebration, the Hall of Fame's Selection Committee Bylaws have been suspended for this year only. The measure will allow for a total of 20 members in the Hall of Fame class, broken down by five modern-era players, 10 seniors, three contributors and two coaches.
After joining the Cowboys in 1989, Johnson built the franchise into a dynasty with a roster that included Hall of Famers Michael Irvin, Troy Aikman and Emmitt Smith. He won back-to-back Super Bowl titles in 1992 and 1993 and had a 44-36 record in five seasons with the team.
Johnson also had a four-year stint as head coach of the Miami Dolphins from 1996 to 1999. He made the postseason three times with the team.
