Would Calzaghe not "spoil Watson's boxing" much as he did to Kessler, if we're accepting that Watson does mainly the same things as Kessler only better?
He would still be swarming in and laying his gloves all over, in a manner that prioritized touches over torque far more than Benn did. (which foiled Benn to an extent)
Also, are we pitting them peak for peak? Are we rolling with the Watson of '91 (but without Eubank II having occurred)?
Then are we talking the Lacy version of Calzaghe? Or one with hands intact?
