Give the Klitschko's their just due

yeah. wanna know what distinguishes them? the ability to fight inside. to pivot, slip and duck shots, counterpunch, deliver crisp combinations. Bowe resembled a young Toney at times.

Lennox was a superb counter puncher, As Taeth stated in his post the KO of Rahman in their rematch is a great example.

If a fighter has size he does not want to pivot, duck shots that means he has to bring himself down and give up his size.

To pivot I think your are confused you don't pivot on every shot you throw, learn some boxing 101 before using the terms to pivot you use your body behind your punches to get maximum effect these guys at 6'6 245+ don't need to twist with every shot they throw.
Don't confuse the technique used in Mike Tysons punch out as the example of how every fighter should throw a Punch

I find it funny you use Bowe as an example because Riddock's speech shows he knew how to do anything but avoid shots
