He needs a brilliant performance. Monroe Jr has a bit of form. It's a perfectly acceptable and respectable opponent. But I think Billy has turned his life around. He was put on trial by Dominic Ingle and he's passed the test.
His body has changed behind all recognition. It's like his head has been put on someone else's body. His mind is right, he sounds right. He will win and I think we will see a new Billy.
I hope so! But we must see a new Billy for him to beat Monroe let alone Golovkin or Charlo...or any other monsters who can fight at 160+
