Uh, Nate absolutely does not have the better hands. He's a brawler with limited technical ability and limited shot selection compared to Conor. Out of all of the high level amateur and some pro boxers I've heard talk about MMA fighters, only a handful have talked about who would be successful in the ring, and McGregor's name was always brought up. Whether it was Mickey Ward talking about it or an Olympic bronze medalist at Mayweather Boxing Club. Nate has been Andre Ward's sparring partner before but he knows neither one of the Diaz brothers would make it far in boxing because they're far from being pure boxers and neither is even a puncher (McGregor is a boxer-puncher). They're scrappers that punch with volume and use their range to overwhelm.
McGregor can fight on the inside and the outside very well, off the back foot, anywhere whether he's leading or countering and he can string together slick combinations that actually hurt his opponents to the head and body.
