i think he would do ok, he is 5'8 and as long as he weighed between 155 and 157 then he would be ok because of the lack off comp up there
His fight against mayorga he struggled. He also struggled against Winky. His biggest wins were Vargas and Oscar.
as a fan of mosely i would not like to see him at mw. the division is very very weak/thin right now but even still. from what i understand williams wants him at ww? i don't understand that either w/ cotto just picking up a strap at 154 but whatever.
but i will say, despite my serious reservations about a move like this, that he could beat sylvester and pick up the IBF title if he really wanted to.
he wasn't nearly as good as at 147. He had difficult matches with washed up Mayorga and Vargas, lost for me against Oscar ( he won the first match at 147), lost twice two Wright. I don't remember if the first match with Forest was at 147 or 154
