Re: Where is Marvin Hagler in your Top Middleweights ATG?
Greb should rank at light heavyweight.
He trained very hard for the Walker fight, but only got down to 159lb.
Most of his significant fights took place at light heavyweight limit. For his relentless style to be most effective he needed to have little excessive weight, yet most of them had taken place above 160lb, so he probably felt that weight suit him better than going below 160lb. There's a legend that he never trained very hard, so this might be some excessive weight, but in fact he trained a lot, it was only a trick he often used to make his opponents believe he was out of shape. He showed up with girls, with a cigar, etc, but it was only playing for the public.
Using the arguments that are often mentioned here, had Greb and his opponents been fighting today, they'd be more muscled and weigh several pounds heavier too, again - they'd still be either 168 or 175-pounders.
