On the eve of his third _ and final _ Olympics, U.S. basketball coach Mike Krzyzewski isn't feeling nostalgic.

 The tears and farewell speeches will come soon enough.

 Credited with restoring American hoops superiority, Coach K said he hasn't considered his legacy or what it will be like when he steps down following the Rio Games.

 "It can never be about a player or a coach," Krzyzewski said Thursday as the U.S. team, favored to win its third straight gold medal, was introduced to the world's media. "You have to be in the moment of the group you coach. I haven't even thought about it (the end) because if you start thinking about that it's very selfish."

  That modesty and sense of team is at the core of the U.S. program's turnaround under Krzyzewski, who is 80-1 while leading the American juggernaut.

  And while he has undoubtedly been helped by a deep pool of homegrown talent, Krzyzewski believes American players have been influenced by the passion of their international counterparts.

  Over the years, Krzyzewski has grown to appreciate how NBA players from foreign countries take their games to new levels when inside the Olympic rings.

  "As good as they are in the NBA, when they play for their countries, something additional is brought out from them and I love it," Krzyzewski said. "I think that sense of nationalistic pride that they bring, brings out even more of their talent. They are great competitors, but they just take it up a notch. That's what I've seen. I love that."

  "I am very respectful of that. I admire it. That's what our team does. That's one of the changes in the last decade for our culture for USA Basketball, we have recognized even more of the beauty of the game internationally. We've embraced it and that's why we've done better and hopefully we'll always understand that and we will continue to be better."
