James' balance was awful in that fight, but he certainly isn't glass jawed. He went heads up with Joel Julio and Angulo and wasn't broken. I think your a little nuts. :nutcase
It had nothing to do with his balance and everything to do with the fact that he does not have a Chin. He was dropped multiple times by bums and feather fisters before the Ishida fight and Angulo wobbled him with a jab and put him on his ass with the follow-up within thirty seconds of the opening bell in their fight. Had Angulo had a shred of ring IQ and picked his shots rather than swarming Kirkland with wild arm punches to the arms and gloves, he would have added another KO1 loss to Jelly Jaw James' ledger. The man doesn't have a Chin and with your lack of knowledge on the subject, I would advise you to leave the Chinchecking to the experts, son.
Williams' Chin is complete glass, he was obliterated by one punch from a blown-up WW with a 50% KO rate and he was wobbled by feather fisted Ishida. He does not have a Chin. As for Rigondeaux, I am nearly certain that like most Cuban fighters he is also harboring a Fragile Glass Mandible but until it is shattered he cannot be placed in these rankings. I am sure it is coming soon, however, because getting flattened by a jab is never a good sign for one's punch resistance.
Here's my rankings: 1. Fraudley 2. Kirkland 3. Khan 4. Litzau 5. Maccarinelli 6. Williams 7. Ortiz 8. Judah 9. Fields 10. Wilder (on suspicion alone)
