What Causes Weak Chin?
Does getting hit repetitively really cause a weak chin?
Commentators say fighters like Chuck Liddel, Jorge Santiago, Big Nog have weak chins because they have taken many shots throughout their careers, but how come some other fighters never slow down from taking repetitive shots?
Boxers like James Toney, Evander Hollyfield, Shane Mosley, Vitali Klitschko don't seem to have weak chins even in the later stages of their careers. Many of their fights were long and grueling and some went to distance (usually 12 rounds in boxing), win or lose they have taken enormous number of shots. How come they still have good chins?
On the other hand, boxer like Roy Jones and Muhammad Ali seems to have weaker chin on the later stages of their careers.
So what causes a 'weak chin'?
