The fight will show what a much bigger man can do to a smaller rival, this isn't just a few lbs and cm in height, its a substantial difference in both.
Diaz reach will play a part in this fight. If it wasn't from the short notice, I would pick Diaz. Well I am picking Diaz anyway. He is going to break Mcgregor apart, slowly but surely.
Nate was eating Mcgregor shots handily. Nate does have a decent chin though. The difference in weight and height, was a struggle for Mcgregor.
