Masterton's retired uniform number is among those on a banner that hangs from the ceiling at American Airlines Center, like it did at Reunion Arena, though Masterton never played for Dallas' Stars.
Mike Modano, who played four seasons in Minnesota, fears most Dallas fans – and probably some Stars players – don't know why Masterton's number is retired or why the NHL has a Bill Masterton Memorial Trophy.
"If people knew his story, I think they would better understand what he meant to the organization and to the sport," Modano said.
Lou Nanne, a longtime figure in Minnesota hockey, talked Masterton into playing for the U.S. national team.
"People in the NHL didn't get to see what Bill could do," Nanne said, "but he was a special player."
Success on, off the ice
Masterton was, in some ways, ahead of his time. College players weren't vogue in the NHL of the early '60s when he led the University of Denver Pioneers to NCAA championships in 1960 and '61.
His performance in 1961 was the stuff of legends. He tallied 80 points in 32 games – an NCAA record then – and led the way to a 12-2 victory in the national final over St. Lawrence for the biggest blowout in title game history. In 1997, Masterton was one of 21 players named to the NCAA's 50th anniversary team.
After graduation, Masterton played in the minors for a few years and also obtained a master's degree from the University of Denver. That led to a job with Honeywell in Minneapolis, and Masterton was on the fast track in business.
"There weren't a lot of guys who were educated in hockey, but Billy was a smart man," Cullen said. "It got to the point where he didn't need to play hockey."
But Masterton still wanted to play, so he rode it out for two years with St. Paul of the USHL and spent a year on the U.S. national team (playing fewer than 28 games in each of those seasons).
Many believed Masterton, at age 28, was done with hockey. But the NHL doubled in size in 1967, and that was too good a deal to pass up.
"We were all trying to catch on, and it was really hard to do back then," said Cesare Maniago, a fringe NHL goalie in the early '60s who then played regularly for nine seasons with the North Stars. "When they doubled the amount of teams, doubled the amount of jobs, you had a lot of guys who got interested again."
And Masterton, living in the Twin Cities when the North Stars were founded, was front and center. On opening night in St. Louis, he scored the first goal in franchise history.
"It was the perfect setup for him," Nanne said.
Differing accounts
There's believed to be no existing video of the Minnesota-Oakland game played on Saturday night, Jan. 13, 1968, at the Met Center in Bloomington, Minn., and there are differing accounts of the events that involved Masterton.
He liked to carry the puck through the middle of the neutral zone, then veer left or right after crossing the opponent's blue line. He would then wait for his wingers and feed one as they came speeding into the offensive zone.
Masterton made his typical play, but Seals defensemen Larry Cahan and Ron Harris read Masterton and tried to force him to give up the puck. Masterton fell backward, and the back of his bare head struck the ice.
"Cahan was a big, barrel-chested defenseman, and he just stood Bill up and ran into him with his chest," said Maniago, in net at the other end of the rink. "It was a clean hit, and Bill just went over backward. You see the hit and you see him fall, and you realize he might be hurt."
Al Shaver, the Hall of Fame announcer who called all North Stars games, said he felt Masterton's head might have landed on someone's skate. Shaver said one fan insisted for years that she saw blood coming from Masterton's head before he hit the ice.
Maniago's wife swears Masterton was out cold, as well.
"She thinks the whiplash of the hit maybe snapped his neck and his brain, and that's why he hit the ice so hard," said Maniago, who has retired to British Columbia. "She thinks he was unconscious while he was falling."
Maniago said Masterton had complained of headaches a week earlier following a hard hit. Still another report stated Masterton was awake when teammates first rushed to him and that he said, "Never again. Never again," before he lost consciousness.
Those words could be construed as Masterton second-guessing either his return to hockey or his decision not to wear a helmet.
The NHL's macho code at the time was only beginning to break down when it came to goalie masks, first introduced by Jacques Plante in 1959. Maniago said he was discouraged even in 1967-68 from wearing one.
"After Bill died, I said to heck with it," Maniago said. "I finally was able to put a mask on."
The North Stars traveled late that Saturday night to Boston for a game on Sunday. They took the better part of the day to get there and then played that night.
North Stars officials were informed of Masterton's passing in the wee hours of Monday, Jan. 15, a few hours after he died. Cullen said he was shocked the news.
"I compare it to the death of Dale Earnhardt," he said. "You never in the world think he is going to be dead. It just seemed like something you've seen a bunch before ... and then ... it just hit you really hard. He was dead."
The 1968 NHL All-Star Game was played one day after Masterton's death despite urging from North Stars personnel to at least postpone the game. The topic of helmets was paramount among the players at Toronto's Maple Leaf Gardens.
Chicago's Stan Mikita, the league's reigning MVP, began wearing a helmet for good soon after the Masterton tragedy. More players followed suit.
"Management was definitely against it," Mikita said of the general practice. "If you put on a helmet and your game dipped the littlest bit, then management would be telling you it was the helmet's fault."
Mikita repeated as MVP in 1967-68.
Honoring the man
Scott Masterton has fuzzy visions of his father, who died when he was only 4 years old. There are memories of eating graham crackers and honey or freezing the backyard patio to turn it into a rink, but he has actually gotten to know his father best through the stories that he has been told over the years.
"What has been great for me is that my mom was able to maintain contact with some of the players or people in management with the North Stars, and we were invited to a lot of team functions," Scott said in an interview last summer in Bloomington. "Everywhere you went, people would have great stories to tell about Dad."
Scott and his younger sister Sally were both adopted. Their mother, Carol, moved back to her native Winnipeg, Manitoba, for about six months after their father died.
"But she always told us it just didn't feel right," Scott said. "We loved it up there and we visited up there every summer, but she felt we had our home down here." Carol died in 2004.
Scott and Sally grew up in the Twin Cities area and are rearing their children there. They said the references to their father are fading, especially since the North Stars moved to Dallas in 1993. But they both work hard to maintain his memory.
The Professional Hockey Writers Association began distributing an award in his name in 1968, and it is seen as one of the most revered in the sport. It's given annually to the player who best exemplifies the characteristics of perseverance, sportsmanship and dedication to hockey.
"I really like what the award is based on because I think that is what my dad stood for," Scott said. "There's a lot of pride in that.
