who has gone 5 divisions and dominated every division???

[TheGreatA]

Armstrong beat everyone from 126 to 147 and was robbed of a version of the world middleweight title as well.

130 and 140 lb weight divisions were around even then but they weren't as important. Armstrong weighed 135-140 for the majority of his career.

He did beat Benny Bass and Barney Ross who were recognized as super featherweight (Bass) and light welterweight (Ross) champions.

Calgazhe, Margarito, Cotto, could all have done it if they wanted to do so.

Calgazhe, Margarito, Cotto, could all have done it if they wanted to do so.

Margarito failed at 154
Calzaghe can't even move up CW and win a title.
Cotto would fail at 160 BIG TIME

ummm......cotto is too small for anything above 147. he's kinda short for 147 as is.

marg's chin wouldn't hold up at 160 or above.

calzaghe? 160 , 168 , 175......then cruiser and heavy?
