White: Diaz fought McGregor at 190 pounds

White says that Diaz was far heavier than measured at the weigh-in. Diaz weighed in at 170.5lbs on the day preceding UFC 202 and McGregor was 168 pounds.

The night of the fight Diaz comes in at 190 pounds. Now, Conor McGregor is [145-pound to 155-pound] guy and if you look at the wars he’s had with Diaz – you can only have so many of those wars in your career man. And it just doesn’t make sense. That’s why we have weight classes. It ended up being an amazing fight but you don’t want to keep doing that.
