One of the big problems with Joshua-Harrison is that - I think most would agree - we now pretty sure that Joshua can punch pretty hard, which was always a question mark in the past. With his accuracy and decent power, Harrison will fold quickly.
Say what you want about Audley, but he still won the British & European titles and challenged for a world title (won't go into that one...).
No link to a source, no where else is reporting this and the thread starter hasn't posted in here since the opening post. Smells like büll****.
