Leading up to UFC 202 it looks as though Conor McGregor has slimmed down and is focussing on having strong cardio, whereas Nate looks to be beefing up.
It should be noted that Nate Diaz has fought most of his career at lightweight. He has taken a few fights at welterweight but his home division has always been 155lbs.
With plenty of time to prepare for a fight at welterweight, and knowing he has an opportunity to have a significant size advantage over Conor, it loos like Nate is bulking up as much as he can.
How big will the size disparity between the two be? If the following six pages are any indication it will be significant.
