MacMillan is the executive director of the Todd M. Beamer Foundation. Beamer was one of four travelers on the United Airlines flight that crashed last Sept. 11.
Four travelers on that flight, including Beamer, are thought to have stormed the cockpit to prevent terrorists from crashing the plane into Washington, D.C. Beamer was heard over a cell phone exclaiming, "Let's roll!" before the plane went down.
"It makes me feel better," Bowden said.
"Things like that you just simply have opinions. You have some people who believe like I do, and you have some people that don't. It's not a sin. Yes, I definitely feel better about it. When somebody asked me if I had called them and asked, I hadn't and I felt. ... I got to thinking maybe I should have. I just had no idea this thing would do what it did. I had no idea."
The Seminoles gathered in their second-floor practice room to listen to MacMillan. Players said MacMillan spoke of the importance of being a team, pointing out that Beamer and other passengers had to help and rely on each other during that flight.
Linebacker Michael Boulware said he was "touched" by the emotional message. Players were given T-shirts - white with an American flag and the slogan "Let's Roll" on the front - as a reminder of MacMillan's visit.
"Coach Bowden had spoken about what it meant before, but now we have a really good, clear understanding of what it means," Boulware said. "It was (emotional). It brought memories back to me and the rest of the team, and it was a very special opportunity to hear his testimony."
Bowden, who met with MacMillan in his office prior to the team meeting, is hopeful the controversy is now behind the Seminoles.
"I think a lot of them still don't understand, thinking that we did it for profit, sell shirts, which never entered our minds, to get publicity for ourselves, that wasn't .... what we do with our shirts, if we could we would never tell a soul about it," Bowden said. "It's kind of just for our team."
