TORRANCE, Calif. Those who doubted that giving Nate Diaz the spot opposite Conor McGregor in the main event of UFC 196 was a good move for business should have seen the scene in Los Angeles' South Bay area Wednesday. Less than 24 hours after the younger brother of mixed martial arts' hardcore antihero, Nick Diaz, was announced as the substitute for injured lightweight champion Rafael dos Anjos against McGregor at Las Vegas' MGM Grand Garden Arena on March 5, the masses flocked to a news conference promoting the impromptu welterweight bout.
