Want to see something weird? Here's NBA All-Star, 2007 MVP, Finals MVP, and 2011 NBA Champion Dirk Nowitzki playing tambourine for the Avett Brothers, apparently attempting to supplant James Harden as the NBA's biggest hipster. The folk-rock harmonizers invited Nowitzki to the stage during their performance at the Verizon Center in Grand Prarie, Texas. He looks like he's having fun! Maybe he's still in the "denial" stage of grief after being humiliatingly swept by the Thunder. CHILL CHILL CHILL WE DON'T WANT ANY BEEF HERE ON PREFIX. Watch Dirk being Dirk below.
