Who did Hopkins beat at MW to prove his greatness?

His biggest wins were small men moving up. DLH who had really already lost to Sturm and Trinidad who spent most of his career at WW.

Then after Hopkins moves up you have loads more men being called up way beyond their optimum fighting weights.

Hopkins wins over Trinidad and Tarver were significant, but no more significant than Calzaghe beating Lacy, Kessler and Hopkins himself.
