Riddick Bowe's conditioning. Early and late.

I checked out some video of Bowe like when he beat seldon in a ko in 1 and he fought at around 225 and looked very good physically, he never was super muscular but being 6'5'' he carried the weight quite well, yet against golota II at a higher weight of 235,physically looked terrible. :D His upper body looked like he was all bones, what was the cause for this, was he dehyrated or should have he fought at a higher weight........... strange conditioning......... :) :o ..
