Eddie Hearn On Khan VS Canelo fight

I get the feeling that Brook actually doesn't want any of these big fights. Yes, he has called out Khan a few times, and yes he did beat Porter, but he had no choice it was his winning ticket so he went for it. Now he has the belt he wants to put money into his pension, so after Khan, I get the impression that Brook is scared of fighting any of the big guns like Bradley, Thurman, Garcia etc.
