basketball, i spent some time with men who are. the nba biggest stars are coming together under one world famous coach who is not only determined that they will win the gold as they did four years ago, but do it with honor. >> lebron with the pitch. show time, lebron. >> just a few days before their first olympic show down, we went to washington to watch some of the greatest athletes of all time in action. team usa 2012. kobe bryant, kevin durant, chris paul, and of course lebron james. all superstars with super egos. two years ago, james created a world of controversy by leaving his hometown team in cleveland for the miami heat, promising them he would bring home the championship. this year, he did. but even james isn't guaranteeing olympic gold. >> if you had the best players,

does that mean you have the best team? >> absolutely not. you have to have team chemistry. you have to have friendship and everyone has to believe in the same goal. >> that's when coach k. comes in. >> sab salutely. >> he is the mike krzyzewski, the best college basketball coach in history. he won international acclaim as head coach of the 2008 olympic team, which won the gold in beijing. redemption after the team failed to make the finals in athens. >> how good is this year's olympic team. >> this year's team has at chance to be extremely good and very unique. >> how do you get the egos to work for you not against you? >> well, we want big egos. you have to have that. but when we walk out of the room, we have those performance egos of, you know, this is what i do at the lakers. this is what i do at the heat. but then you have the ego of

being a part of something bigger than you. >> but they're not there yet. >> this group right now is not a team yet. it's becoming a team. and that's why the stop in washington is the process of it. we hope to be that team in london. >> and he has a plan. you might call it a military operation. from a man who graduated from west point. >> we needed to have a stop where we could feel what we're doing. you look at your uniform, you see and can hear the national anthem and all that, but you need to feel some things in order to own this. >> his strategy, turn this group of superstars into a band of brothers by introducing them to men and women whose lives depend on team work. >> i think that's what i learned the most in the military is that you're never going to do it alone. and you need to trust one another. in other words, we're bolder if

when we say charge, we know that everyone is going to charge with us. if we're not sure and we have to look back, we have never really charged. and that's the experience that i want from my team. where they never look behind them because they know their brothers are with them in a moment's notice. >> so they practice in front of military families and shot hoops with service members. coach k recruited his old friend and chairman of the joint chiefs of staff general martin dempsey for the mission. >> we want these soldiers to step forward, take the flag from their shoulders, give it to each of you and ask you to carry it with you as you go to represent this great country of ours in london. >> that is a symbol of pride. it's a symbol of comradery, it's a symbol of trust that we will go out there and do what we need to do to take care of business. >> but coach k wasn't done with this operation.

the team was granted the rare privilege of placing a wreath at the tome of the unknown soldier. >> but us to stand there in the midst of greatness, selfless service, it actually brought some tears to some of the guys. it brings tears to my eyes right now. we now as a team representing our country have the chance to be among heroes who have represented their country at the highest level and paid the greatest price. >> if you look at some of the tomd stones and see the years that i lost our lies and fought for our freedom. >> you believe that that trance plaits into the kind of feeling and greatness that you need for these guys to play to win? >> absolutely. a lot of times we don't allow ourselves to be touched. nothing enters into our heart. we got touched here in washington, d.c. and hopefully it will be the touch that we

need to -- not just the gold medal winning performance, a performance that's worthy of respect. that's our goal, is to win and win the right way. >> well, team usa's first game will be sunday against france. we are rooting for you. next up, he is the man taking a little block buster bourne franchise chiez. we get to know the real jeremy renner. time out. sweet.
