COLUMBIA, Mo. — Craig Kuligowski heard the words, but at first they didn't register.
In nearly three decades in college football, the University of Missouri defensive line coach had come to view summer team-building sessions as a typically uneventful training camp exercise. So he wasn't expecting different on a sweltering day last August when he gathered 15 players in a nondescript, windowless meeting room on the first floor of the Mizzou Athletic Training Complex.
There, beneath seven black-and-gold placards professing an adherence to teamwork, camaraderie and character, one of the players tested whether those were core values or just empty words.
"I'm Michael Sam, a defensive end," the player said. "I'm gay."
Just like that, one of the toughest players on one of the toughest teams in the toughest conference in college football outed himself to his position coach and teammates.
That kind of revelation, it had long been assumed, might have apocalyptic consequences in a football locker room where bravado and homophobic slurs can be commonplace.
The reaction that day: "Everybody's like, 'Oh well, there you go'," Kuligowski recalled Tuesday while sitting in the same room under the same placards.
Over the next weeks and months, Sam's decision to come out united the locker room rather than divided it. Instead of turning their backs, his teammates let him know they had his back — and a team that had won only two conference games the previous season advanced to the conference championship game, defeated Oklahoma State in the Cotton Bowl and finished 12-2.
Sam, a starter but not a star in most of Missouri's 2012 games, elevated his play to become the Southeastern Conference's defensive player of the year and a first-team All-American. His teammates voted him Missouri's most valuable player.
"This is probably one of the issues that united them," Kuligowski said of Sam's pronouncement. "Our guys, they got into a protective mode of where if somebody said something bad about him, they're going to have to face all of us. He's part of our family and we love him and we accept him as he is."
But it didn't have to turn out that way.
"It could have been a very huge distraction to our team," the coach said. "No question."
Even before Sam's announcement , the vending-machine-sized lineman's sexual orientation was a poorly kept secret.
The fifth-year senior had quietly come out to two teammates a year earlier. And even before Sam told more of the team, a reporter had approached associate athletic director Chad Moller with a question about an unnamed gay football player.
Sam, 24, didn't try too hard to hide his homosexuality but hadn't spoken publicly about it until ESPN and the New York Times published articles on Sunday. Sam was not available to be interviewed for this article.
"He wasn't ashamed of it, but he didn't want to necessarily bring all the attention to him," said Kuligowski, who recruited him to Missouri. "He didn't talk about it, so nobody else talked about it."
Indeed, none of Missouri's 127 football players discussed the issue in any detail outside the locker room. Nor, for that matter, did the local media pry, allowing Sam to make the announcement in his own time.
"A lot of people knew, but nobody really cared that much," said Tyler J. Adolphson, a senior communications major from St. Louis. "I overheard it being casually mentioned at several bars on game days, but everyone's reaction was always the same: 'Oh well, he's having a hell of a season.' "
Pat Ivey, Missouri's strength and conditioning coach, also heard the rumors. For three years Ivey has held diversity seminars for the school's athletes, and last April he broadened his session by including the You Can Play project, a campaign to protect opportunities for athletes regardless of their sexual orientation.
