the weakened non-winning eubank who had just killed himself to drop 2 divisions in 2 weeks, and wanted to explain away his loss to someone he should have beat when prime. but of course, that's the only example u have of joes "power"...which mysteriously disappeared for the next 12 years.
I think Calzaghe could and probably would defeat McClellan. McClellan fought almost exclusively at a lighter weight. Plus you can't dismiss Calzaghe skills and I believe he has a superior resume. I think another Mac, McCallum would be a tougher fight than McClellan.
40something Hopkins had been unable to knock people down, only exception being calzaghe whom he floored with ease. Calzaghes chin is therefore weaker than guys like cloud, dawson. And JOe chins is therefore weaker than smaller men than him middleweights like taylor, pavlik, tarver, Eastman, winky, Ornelas and Roy Jones Jnr. et al.
