Anti-china chin nutrition? Is it possible?

From what I understand hydration or lack there of can play a part in an ability to take a good punch.
If you have a boxer who is having probblems making weight and not eating and drinking before the fight he is going to be week and the shots he takes are more likely to catch up with him than it would a boxer who has no problem with the weight, who has been eating and drinking up to the fight.
Khan's loss was at 135. At 5'10" it was a weight he was likely to out grow at some point anyways. Prescott is not a bad puncher himself. I think someone was going to stop Khan at 135. Rather it was Prescott or someone else. There are still questions in my mind about Khan's chin Malignaggi is not a puncher. However I think 140 and 147 will prove much better for Khan.
