sports right now. Michael Sam is returning to football this morning for the first day of training camp for the St. Louis rams of the NFL as the first openly-gay player drafted by the NFL, he knows he has a lot to prove on and off the field. Sat down with him after the espys for the Arthur ashe courage award, and he's ready to tackle the task at hand. What have you been doing since draft day to prepare for that first day? Camp? Training, working hard. I lost 12 pounds since I came into mini camp. I'm doing my job. Don't you worry. The St. Louis rams select Michael Sam. Reporter: He was a late draft pick. This was a moment when he questioned whether or not he would make it to the NFL. What was going through your mind? I was kind of second-guesses myself. Maybe football turned its back on me. Maybe I was like, maybe I shouldn't have done what I did, you know -- You mean coming out publicly like that? Maybe -- I had so many motions in my head, and then I felt a touch over my shoulder, and it was Vito, and I was just -- I was, like, I don't care what happens. You know, I know I did the right thing in my heart. Whatever happens happens. I'm going to move forward. Sg zblsh a Reporter: And now to St. Louis. Home state. Going down the road. And finally getting the opportunity to do what I love. Not a lot of people can say that. I mean, like I said in my speech, football raised me, taught me about hard work, discipline and team work. Reporter: Last Wednesday Sam attended the espys, honored with the Arthur ashe award for courage. Arthur ashe was not just brilliant, he was great too. He put all the wisdom of the world in three short sentences. Start where you are. Use what you have. And do what you can. Reporter: What was that moment like for you? To be up there accepting that award? It was nerve-wracking, first off. So many others well-deserving of that award. So I share this award with everyone who has the courage to tell their parents, to tell their peers, to tell their friends, anyone that, hey, I'm comfortable who I am. I don't care what you think, this is who I am. And the Arthur ashe award goes to that person as well. Well-said. And much more later of my interview with Michael Sam on espnw in the coming weeks.
