RG did have one fight at 140 almost exactly 2 yrs ago. Casamayor. So his only fight at that weight was against a shot/faded 135 pound fighter. And he got dropped late in that fight.

if Aydin can do decent bodywork throughout the fight he has a chance at catching RG in the last 3-4 rounds.

A fading Katsidis, who was beat up throughout the bout, was able to still hurt RG a bit later in their fight with bodyshots.
