Excuses. He was a little past prime, but only 33 and 5 years after his career best performance. He'd beaten Zivic the year before. As Welterweight Champion his management dodged the best welterweights of his day Either way no version of Armstrong is going to be competitive with Robinson because he isn't nearly as good a boxer. Neither would he have been competitive with Burley or Holman Williams.
How many times have you seen this fight to be so sure that he never used hook behind his jab or never doubles jab? Are you so certain about that? I can break this fight down if you wish. So footwork and head movement are not a technique? I've seen at least a few 1-2s in this fight. Compare that to stationary, unimpressive Canelo then. He split the series with Greb and he lost Tunney in his last fight at the age of 34. You are insane...
You have to be next level of old time boxing hater to believe that Canelo is much better fighter than Tommy Gibbons.
Because he fought for survival. It wasn't easy to last the distance against Dempsey when you are a LHW.
Even if Armstrong was at his absolute peak, Robinson significantly bigger. Armstrong was champion at featherweight FFS
Only a hater can attack a natural FW that he ducked someone like Burley, who was a MW for most of his career.
