what way do you circle ring against southpaw?

You have to circle to your own left against a southpaw, because you can avoid his (left) powerpunch that way by circling away from it.

 

You circle to your left to keep them off balance and make them reach with there power hand circling to your right would be walking right into their power hand I dont know what the commentators were talking about Khan pretty much fought perfectly that night.

 

Circle away from their back hand (in this case circle to your left), thus putting your front foot outside of his, making him extend himself to reach you (IE him off balance).

This is exactly what JMM did to Manny Pacquiao, effectively.

 

And what if the man has great great lead hook? Do you really want to circle into that?

 

Hooks are easier to see coming and easier to guard against the brain doesn't notice a straight punch as quick as a hook were you flail your elbow and turn your body as odd as that might sound.

 

what hook?

 

obviously you're not just gonna rotate in a circle

 

To your own left, away from the power hand and so you can keep your left foot outside their right.

I don't know why Khan was circling right, but he must have had his reasons. Maybe he was more concerned with Judah's right hook than backhand.

 

Mostly to your own left, but you need to mix it up abit

 

Indeed, but the thing that has traditionally the case is that, unlike orthodox fighters, southpaws almost without exception are heavily relient on their power hand, the left hand. That's what makes southpaws such a strange bunch: they're not just mirror images of orthodox fighters, who can generally have a left hook or a straight right as the hand that does the damage. Overwhelmingly, the back hand with southpaws is the hand that does the damage. The fact that this is true with the vast majority of southpaws is the reason why a southpaw fighter that has another weapon in his lead hand, such as the right hook that Pac developed, is such a formidable opponent. Traditionally southpaws are one-handed fighters: they have a pawing jab which works as a range finder, sledge-hammer left hands and good left uppercuts and left body-shots. Add a right hook to that arsenal and they're hard to beat.
