I know, i'm just pointing out that it is weird to say Wills was fighting an undersized opponent, when Dempsey did just the same on several occasions. Whether Wills had a bigger size advantage or not is irrelevant, since we're talking heayvweights and not pound for pound.
Langford had considerable experience when he was stopped by Joe Jeannette and Young Peter Jackson but I would not consider him to have been in his prime in these fights.
I think the Gibbons win was a very good one and Gibbons was only stopped once in his last fight ,the weight diffential between Dempsey and Gibbons was only 12 1/2 lbs, not the 40lbs plus Norfolk conceded to Wills ,plus they were around the same height.The Carpentier fight was a mismatch I think,but a very lucrative one.
Would be a better comparison to say Wlad ko'd Toney or Tua or lets say Hopkins/Calazage beat a few HW contenders, then its a good comparison If your discounting Wills win over the highly rated Norfolk jsut because hes a LHW you have to do the same for other fighters. So I presume you are discounting some of Dempsey's better wins over former light heavies too, ie Gibbons, Carpentier, Miske (coming off a loss to Norfolk), Levinski
