contests arent decided on arms alone.
don't take a page out of ND's old tired and flawed book..
of course contests are not won on arms alone.
contests are not one on anything in isolation
they are won by establishing a series of advantages via physical attributes that combine to give a superior physique.
and when it came to a large and important bodypart like arms, a lot of people had an advantage on Dorian..
just another piece of the argument that dorian won because mainly because of size- that was first and foremost on the judges agenda.
he did not win by having better quality.
