khan has a weak chin, but khan isn't training his chin, instead he's training to get better to prevent his chin getting hit, so that's abit of a stupid comment mentioning chin and training. it seems like every fighter that doesn't have good durability should just stop training and let their opponents hit them. some of you are dumb. luckily a few boxers who don't thrive in the chin department, thrive in other departments such as speed and so on to give themself less chance getting caught. khan might lose, khan also is good enough to outbox maidana. we'll have to see.
