Boxing champion Adrian Broner may believe that his decision to not join Jay Z's Roc Nation Sports was good, but for others, it didn't seem smart. One of those others turn out to be 50 Cent, who also happens to be a boxing fan himself.

Broner recently displayed his dislike for the Roc Nation Sports on TMZ Hollywood Sports, sending both shots to Jay Z and Rihanna. Check out the video below.
