Like others have noted Mingus is easy to hit and Canelo is a solid counter puncher. It all adds up to being a bad night for Munguia, who will have some moments but in the end will get beat up.
OP has an interesting take but the answer is 'probably not'. Canelo has genuine power and getting teed off by him on the face is a recipe for disaster. I don't think Munguia has the skills to avoid getting first a zombie face and then getting knocked out. If Munguia does well then I suspect its the end of the road for ginger.
Canelo has had a lot of fights, he has to get old in the ring at some point. I think Jamie has improved over the last couple of years. So I’m picking a pretty good scrap, I don’t really care who wins tbh.
