PBF vs Harry Greb

How is this thread going on when it's regarding a fighter nobody has seen in action?

 

In any case i'll play along, i take Greb given his bigger size and from what i've read his style is something like Armstrong just non stop punching except more unorthodox and punching from all angles. Given he was only Ko'd twice in over 300 bouts (fighting middles, light heavies and havies) under understandable circumstances it's fair to say Mayweather won't be Koing him. His record is also VAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAASTLY superior.
