No, I don't think so too. If the fight will end in a stand-up fight Diaz will just have a sore face and body with the added loss.
The only chance I could see is thru submission which will be a difficult task to achieve when fighting Chimaev because no one had successfully managed to take him down yet.
Then, if ever by some miracle it does happen, Nate has to worry about the counter with Chimaev having the same skills in submission.
A win from Nate here will almost look like how Edwards won. Unexpected.
I'd say he has more chance on the feet than on the ground, and I believe that speaks volumes since I don't think he has much chance on the feet. I'd be very surprised if he manages to submit Chimaev, but you could argue that crazier things have happened in the last year, we've had massive favourites, including this weekend just gone lose, so I can't be 100% sure obviously.
However, I do consider this one of those fights were the favourite wins 9.5 times out of 10. Honestly, I'd love to see Diaz win, and while not being a fan of either of the fighters I'll be hoping Diaz pulls off the upset.
Yup, definatelly more chance in standup than wrestling or bjj. He can't match Chimaevs wrestling skills, and his BJJ i honestly outdated for modern MMA. He would have to have Brian Ortega type of skills and confidance off his back to even atempt something on Chimaev. On paper Diaz is a huge underdog here, but as you said, stranger things have happened.
