Straight from the horse's mouth:
What was that about publicity stunts?
Ultimate Fighting Championship (UFC) party pooper Nate Diaz, who derailed the Conor McGregor hype train at UFC 196, is probably tired of reading all those ridiculous headlines about "Notorious" crossing over to boxing to throw hands with pound-for-pound great Floyd Mayweather Jr.
Not because the fight is never going to happen, but rather because McGregor is not the most qualified man for the job.
That honor belongs to Diaz, according to his recent comments on Twitter, who can more than hold his own against "sweet science" titleholder Andre Ward (proof). Whether that materializes into an MMA vs. Boxing crossover remains to be seen, but it's not like it's never happened.
For better or for worse.
