Jay Z is back into boxing with Roc Nation. He even hired the guy that worked with Sweet Lou dibella all those years.I used to see Jay Z at Zab's fights and after-parties and he is a big boxing fan. He is one smart businessman.
I think he doesn't like Al Haymon too much either considering the lawsuits against Haymon brought by Beyonce after he tried to rip her off. Boxing sure does have a spectrum of people involved one way or another.
