20. The Rivers
The Los Angles Clippers coach Doc Rivers has definitely got something right. As well as being a very good player in his own right, his sons have burst onto the scene. Austin plays with his dad at the Clippers, while Jeremiah played NCAA ball for Georgetown and Indiana. Meanwhile, Callie played volleyball for the Florida Gators.

However, it goes even further than that. Doc’s uncle is nine-year NBA veteran Jim Brewer. Some special genes definitely run in the family. It doesn’t stop there, as his cousin Byron Irvin starred for the Portland Trail Blazers, while another cousin, Ken Singleton, is a former MLB outfielder.
