After retiring from football he became a business partner and advisor to Edward J. DeBartolo Jr., former San Francisco 49ers owner.
Born in Youngstown, Muransky played football for Cardinal Mooney High School where he was affectionately known as "Big Ed" by family and teammates.
In 1976, he won All-Steel Valley, All-NEO, and All-State honors, and received the Mack Truck Award, given annually to the most outstanding high school lineman in the Youngstown area.
[1] Highly recruited by numerous "blue chip" schools, Muransky chose to play collegiate football at the University of Michigan.
The 6-foot-7-inch (2.01 m), 320-pound (150 kg; 23 st) lineman was a key member of the 1980 Wolverines, coach Bo Schembechler's first bowl-winning team.
[1][4] He was part of a 1981 team that had five All-American honorees (Anthony Carter, Butch Woolfolk, Bubba Paris and Kurt Becker).
After we had enjoyed our fourth plate of prime rib, mashed potatoes, corn and Yorkshire pudding, Bubba asked what the record was, and they said 7 cuts.
When they delivered the 8th cut to me, the media started to gather around my table, Bo walked by and let me know what he was thinking without ever saying a word.
"[7] When the Wolverines returned to Pasadena for the 1981 Rose Bowl, "Bo made it a point to come to the back of the plane and talk to me and Bubba Paris.
He wanted to let us know that my record from a couple years earlier would not be in jeopardy because we were going to be sitting with him at the Lawry's Beef Bowl.
"[7][8] Muransky is also remembered for a cameo appearance in the 1983 film The Big Chill: "I was in the theater watching it, not knowing what was going to happen.
In the team meeting the next day, Schembechler walked into the room and wrote "Ed Muransky" and "Stan Edwards" on the chalkboard, and then barked out, "The rest of you are quitters.
[9] According to the coach, Muransky and Edwards were the only two who played with intensity against Wisconsin, and Bo left it to them to motivate the rest of the team.
Muransky played for an offensive line that included Pro Bowlers Henry Lawrence and Todd Christensen.
[14] The team was led that season by quarterback Jim Plunkett and future Hall of Famer Marcus Allen, who rushed for nine touchdowns, caught two and threw three on a 4–7 passing performance.
[21] In the late 1990s and early 2000s, Muransky became the most trusted advisor and business partner of Edward J. DeBartolo Jr., heir to a real estate empire and former owner of the San Francisco 49ers.
Eventually, Muransky who is said to have a keen business sense, became DeBartolo's most trusted advisor, which caused a rift with Carmen Policy, 49ers president.
The project required approval of the state gambling board and resulted in a highly publicized bribery scandal that ended with the conviction of former Louisiana Governor Edwin Edwards on 17 counts, including racketeering, extortion, mail fraud, and wire fraud.
In order to secure licensing of the casino, Edwards and associates allegedly solicited bribes from DeBartolo, including a briefcase filled with $400,000.
