Is it possible that a fighter is susceptible to a certain punch more than any other?

[CokeCider]

For example : Ive seen Amir Khan Eat many right powerful hands and stay on his feet, but when it comes to the left hook he's been hurt many times from weaker punchers.

Or Miguel Cotto , he has a good chin to begin with he's been hit with all types of punches, but smaller guys like Zab and Mayweather have hurt him with an uppercut.


Can fighters possibly have weaker points on their chin?

[Larry the boss]

Some fighters are just blind to certain punches
