Problem: Given the question: Information:  - Michael Rabold ( born March 12 , 1937 ) was an American football offensive guard who played eight years in the National Football League .  - The American Football Conference (AFC) is one of the two conferences of the National Football League (NFL), the highest professional level of American football in the United States. This conference and its counterpart, the National Football Conference (NFC), currently contain 16 teams each, making up the 32 teams of the NFL. Both conferences were created as part of the 1970 merger with the rival American Football League (AFL), with all ten of the former AFL teams and three NFL teams forming the AFC, and the remaining thirteen NFL clubs forming the NFC. A series of league expansions and division realignments have occurred since the merger, thus making the current total 16 clubs per each conference.  - The National Football Conference (NFC) is one of the two conferences of the National Football League (NFL), the highest professional level of American football in the United States.

A series of league expansions and division realignments have occurred since the merger, thus making the current total 16 clubs per each conference.  - The National Football League (NFL) is a professional American football league consisting of 32 teams, divided equally between the National Football Conference (NFC) and the American Football Conference (AFC). The NFL is one of the four major professional sports leagues in North America, and the highest professional level of American football in the world. The NFL's 17-week regular season runs from the week after Labor Day to the week after Christmas, with each team playing 16 games and having one bye week. Following the conclusion of the regular season, six teams from each conference (four division winners and two wild card teams) advance to the playoffs, a single-elimination tournament culminating in the Super Bowl, played between the champions of the NFC and AFC.  - Christmas or Christmas Day (meaning "Christ's Mass") is an annual festival commemorating the birth of Jesus Christ, observed most commonly on December 25 as a religious and cultural celebration among billions of people around the world. A feast central to the Christian liturgical year, it is prepared for by the season of Advent or the Nativity Fast and initiates the season of Christmastide, which historically in the West lasts twelve days and culminates on Twelfth Night; in some traditions, Christmastide includes an Octave. The traditional Christmas narrative, the Nativity of Jesus, delineated in the New Testament says that Jesus was born in Bethlehem, in accordance with messianic prophecies; when Joseph and Mary arrived in the city, the inn had no room and so they were offered a stable where the Christ Child was soon born, with angels proclaiming this news to shepherds who then disseminated the message furthermore. Christmas Day is a public holiday in many of the world's nations, is celebrated religiously by the vast majority of Christians, as well as culturally by a number of non-Christian people, and is an integral part of the holiday season, while some Christian groups reject the celebration. In several countries, celebrating Christmas Eve on December 24 has the main focus rather than December 25, with gift-giving and sharing a traditional meal with the family.  - The Super Bowl is the annual championship game of the National Football League (NFL), the highest level of professional American football in the world. The game is the culmination to a season that begins in the late summer of the previous calendar year. Normally, Roman numerals are used to identify each game, rather than the year in which it is held. For example, Super Bowl I was played on January 15, 1967, following the 1966 regular season. The single exception to this rule is Super Bowl 50, which was played on February 7, 2016, following the 2015 regular season. The next game, Super Bowl LI, scheduled for February 5, 2017, will follow the 2016 regular season.    What entity does 'mike rabold' has the relation 'date of death' with?
