What strategy can give Pacquiao a measure of success?

[ICB]

When Hatton charges in, a little sidestep followed by a hook to the jaw ought to do it.

I'm think that a straight left would be even better.

Perhaps, but a sidestep/hook increases the likelihood of a headbutt collision with the ringpost.

Hopefully this time Ricky Hatton just misses the ringpost. And headbutts Floyd Mayweather Sr as he is flying out the ring. Nothing would please me more.
