Pointless match for McGregor. He should be defending his belt. Cant see him beating diaz with a limit ground game. Its not something you can learn in a few months.
Of coarse conor could hit him with a shot like he hit aldo with but diaz does not have a weak chin and can also box.

On a side note i am not being funny here but does diaz have a problem dealing with people , his social skills are Neanderthal at times.
