We should all be thankful for Instagram. Without the picture-sharing service, we wouldn't be receiving constant gems from the USA men's basketball team. Like this photo of Kevin Durant, James Harden and Deron Williams taking a Segway tour of Barcelona.

Or this picture of half the team asleep on the plane.

On Monday we received another gift, this time thanks to Williams. The Brooklyn Nets point guard caught coach Mike Krzyzewski finishing up some yoga before practice. It's not the most flattering photo of Coach K, but we can't all look good when we're in the downward dog position.

In all seriousness, photos like these provide an interesting peek into the lives of some of the most famous athletes in the world. Rather than having to wait 20 years for the documentary to come out, we're given a behind-the-scenes look at the Dream Team in real time.

Thank goodness for Twitter.
