WASHINGTON - Dancers were performing during breaks in the action. Dunks were greeted with "MVP!" chants.

Mascots, merchandise giveaways, and hot dog stands had the feel of an NBA arena, not the U.S. Olympic men's team's workout.

Of course this was no game. As Allen Iverson would say: We talkin' about practice.

The U.S. Olympic basketball team went through a most unusual workout Saturday, an open practice for military personnel and families at the D.C. Armory that felt more like Midnight Madness on a college campus than a team getting ready to defend a gold medal.

"We understand it's kind of - actually every day with USA Basketball is a little bit different," coach Mike Krzyzewski said. "Not bad, but certainly different. But today was different in a very spectacular way. All of our guys were proud to be here."

And while France, the Americans' opening opponent in London, was playing an exhibition game against fellow medal contender and reigning Olympic silver medalist Spain on Saturday, the Americans were taking part in what felt like a pep rally, a workout environment loaded with distractions that called to mind Rocky's training camp before his first fight against Clubber Lang in "Rocky III."

Yet because of the people watching, and Krzyzewski's military background, the day was worth it for the Americans.

"Coach K talked about this being such a great day for USA Basketball, but for America, and understood the significance of it," said ESPN analyst Jay Bilas, who played for Krzyzewski at Duke and served as the emcee of the practice.

Krzyzewski played and coached at the U.S. Military Academy and attained the rank of captain before resigning from the Army in 1974. He has had a career-long dedication to USA Basketball, being involved with 12 teams as a head or assistant coach.

Bilas said when Krzyzewski and Jerry Colangelo began putting together the national team program in 2005, they sought to emulate the military in some ways. Service people were involved throughout the day, from a shooting contest in which a representative from each branch teamed with a U.S. player, to a moving moment at the end of practice in which soldiers gave the American flag patch from their sleeve to a U.S. player to carry to London.

"Just being here in front of these guys, the troops and the military, you can't put into words how that made us feel," forward Carmelo Anthony said.

Syracuse didn't hold Midnight Madness, the popular event in which teams hold a public workout at midnight on the first day practice is allowed, in Anthony's lone year of college. But he experienced what it felt like Saturday, going through drills before a sometimes loud crowd of thousands of fans.

"I never heard nobody cheer in practice before," Anthony said. "Coach K usually don't let nobody talk in practice, but I don't know how he was going to control to this crowd today."

The crowd included Joint Chiefs of Staff chairman Army Gen. Martin Dempsey, who dined with the Americans on Friday night, Secretary of Education Arne Duncan, who played at Harvard, and former Georgetown stars and gold medalists Patrick Ewing and Alonzo Mourning. They sat with their college coach, John Thompson, who understood why the Americans' motivation Saturday.

They will have a normal workout today before playing an exhibition Monday against Brazil, and believe Saturday got them more prepared for it, despite the unusual circumstances.

"It was fun, especially getting to play in front of the men and service women that protect our country," forward Kevin Love said. "So it was fun to be here play with these guys and put on a little show for the fans."
