Interesting. Khan and Wilder have two of the glassiest jaws in boxing today, and Gamboa and Rigondeaux have proven shaky chins. Ward's punch resistance problems haven't been evident for awhile, but I suspect you are right and they will reappear. Garcia is a new one on me, I must admit. What are the indications you've seen of his mandibular weakness?
Can't believe nobody mentionned Wlad yet. Considering the guy's size, he probably would be P4P top 3 on such a list.
You're right. Wladimir has been put down hard multiple times in the last 5 years. And shaken even more times in that span. Chambers buzzed him. Pianeta got to him. Haye almost killed him!
He wouldn't even be in the worst 3 for his size. Fury, Price, and from what others say, Wilder, have worse chins. Khan, Mitchell, Kirkland, and Fury are the worst I can think of.
