RIO DE JANEIRO – It’s hard to believe that there were unchecked items on Michael Phelps’ Olympic Bucket List, but there were. Until Wednesday.

In a flourish, the most decorated Olympian has now rounded out the greatest of all five-ring résumés with two new honors: he was voted a U.S. swimming captain and the U.S. flag bearer for the Opening Ceremony. That means he also will attend the Opening Ceremony for the first time in five appearances in the Summer Games.

“It’s a dream come true to lead our country in this Olympics,” Phelps said at a news conference here Wednesday. “It’s something I honestly never thought I’d have the opportunity to do. I think I had the biggest smile on my face you could find. I probably shed a few tears, just of joy.”

In his final Olympic incarnation, there is yet another new side to the constantly evolving Michael Phelps. He now is a true global citizen. He now is a true leader of men and women.

As recently as a month ago, at the Olympic swimming trials in Omaha, Phelps said he was unlikely to walk in the Opening Ceremony. Most swimmers don’t because their competition begins the next day, and the hours spent on your feet are antithetical to the rest-rest-rest mindset those athletes take into a major competition.

But for the first time since 2000, Phelps is not competing in the most grueling of events – the 400-meter individual medley, which is contested on the first day of the swim meet. His first swim isn’t likely to come until Sunday as a member of the 400 freestyle relay. (Nobody was confirming his presence on that relay, but a brisk time trial swim during training camp last week in Atlanta almost assuredly put him on that team.)

Given that decrease in workload – and given the honor of becoming just the second swimmer in American Olympic history to carry the stars and stripes – Phelps was eager to lead his teammates and countrymen into Maracanã Stadium.

But he still had to clear it with his forever coach, Bob Bowman, who also is doubling as the head coach of the American men’s team.

“On a scale of 1 to 10, how much would (walking in the Opening Ceremony) affect me?” Phelps asked Bowman. “If it’s 8.0, there’s no question I’m doing it.”

Bowman teasingly gave Phelps a 7.8.

“I said, ‘It’s a no-brainer. I’d love to do it,’ ” Phelps recalled.

So the 31-year-old will get a new experience in his final go-round. But for all the symbolism of carrying the flag, the substance of being a team captain is even greater.

Just because Phelps was the best swimmer on the American team in 2004, ’08 and ’12, that didn’t mean he was the best leader. He was fine with letting that responsibility go to others.

For one thing, he was the busiest swimmer at each of those Games, given the workload that goes into winning 22 medals. But Phelps also was more comfortable closing himself off in his own cocoon of greatness and focusing on himself.

“I think in 2008 and 2012 Michael didn’t think he was a leader, let alone a captain,” said former breaststroker Brendan Hansen, a teammate of Phelps’ on both those Olympic teams. “I remember talking with him about speaking up in team meetings because his experiences and mindset were so valuable to the team. He did a much better job in 2012 – but from what I’ve heard about 2016, he takes captain very seriously.

“He very much wanted to be part of the team and not lead it in ’08 and ’12. The team support was what he was looking for. But boy did he lead by example in his races those Games. He inspired us all to stop thinking average and take on the world.”

Phelps well could lead by example in the pool here, too. He is entered in three individual events and likely will swim two relays, which means his record totals of 22 medals and 18 gold should increase significantly before he retires at the end of this meet.
