Team USA athletes get video send-off

Some athletes -- such as Tyson Chandler -- did fan Q-and-As via Facebook and Twitter.

Other athletes -- most of them, actually -- were featured in the above video, a two-minute tribute showing some of their greatest moments.

No matter what, all 530 Olympic athletes have been named to their respective squads and will represent Team USA at London 2012.

The Games begin July 27.
