Bute has a good chin. Kahn is a lot more susceptible, especially with ongoing talks about him fighting Mayweather.
Khan because he takes on Bradley in July. Whereas Bute would presumably take on a P4P caliber opponent in his 3rd fight from the 3 fight contract. Plus, McCloskey is a better puncher per weight than Magee is. And, Khan's chin has been shaken in the pros, Bute yes, but he did get up (even if it took 14 seconds).
Don't fall for this idiot's games. First he compares Khan with Donaire, and now he's comparing him with Bute.
Why not make a poll with people in the same division? The correct answer is neither. If Maidana couldn't KO Khan, no one will be able to in the near future.
Exactabox, you're the shittiest poster on this board. Only one place for you, and that's the Ignore list.
