Michael Sam made history in becoming the first openly gay player drafted into the NFL. But he insists he does not stand alone.

Sam declined to estimate how many gay athletes play in the NFL, but he said Thursday that several players contacted him after the St. Louis Rams made him a seventh-round draft pick last year.

"I am not the only gay person in the NFL," Sam said. "I'm just saying there are a lot of us. I respect the players that did reach out to me and had the courage to tell me that they were also gay, but they do not have the same courage as I do to come out before I even played a down in the NFL.

"The players who have reached out to me and told me about their sexual orientation, it just means a lot. But I will never say anything about who they are, what teams they are on. I'm just saying there's some famous people, and I'm not the only one."

Lavin, Tyndall exit suddenly

Coaches exited under peculiar circumstances Friday. St. Johns' fired Steve Lavin after his best season, and Tennessee fired Donnie Tyndall after his first season.

In announcing Tyndall's firing, athletic director Dave Hart cited an NCAA investigation still underway at Southern Mississippi, where Tyndall coached before taking the Tennessee job. Hart said Tyndall had acknowledged to him that he deleted e-mails that would have been of interest to the NCAA.

"Knowing what I know now, is that a mistake?" Hart asked about hiring Tyndall. "Probably."

Lavin's team went 21-12, the most victories in his five seasons at St. John's, but the team lost in the NCAA tournament's first round. St. John's qualified for the tournament in only his first and last seasons.
