I honestly wonder if you take RJJ out of the picture who would be the best guy at or around the middleweight division over the years
Calzaghe? Hopkins? Hagler? Monzon? Leonard? prime James Toney? Michael Nunn(had he stayed away from drugs)? Gerald McClellan had he not been so badly damaged before he reached his potential.

Especially the first four were all great at/around MW, it would be interesting to see them all go at it.
