Sharkey might be, but his ideal fighting weight was less than the Cruiserweight limit. Plus, in my view, Adamek was tougher (both mentally and physically) and more consistent - so, it is as reasonable to doubt it, yes.
Sharkey was at his best around 195 lbs, same as Adamek's best weight. Sharkey started his career at 197 lbs, Adamek started at 177 lbs...
Sharkey seems to have been more sensitive to not training down to his ideal weight, whereas Adamek grew into heavyweight and got some reasonable results there - against bigger men, on average, than Sharkey managed.
You just totally moved the goalposts. We aren’t talking about records. Sharkey did not beat aggressive 240 pounders. Those “decent” fighters that Arreola lost to in his prime were better than Sharkey.
But he beat agressive 220 lbs Godfrey. Do you really believe that Kownacki, Stiverne or Adamek were truly better than Sharkey? If so, we have nothing to talk about.
Arreola was not in his prime for Kownacki. Stiverne and Adamek were better. Godfrey wasn't the same size as Arreola. Sharkey was also the 11th man to beat him.
Stiverne better than Sharkey? What's next? You're right, Godfrey was 220 lbs of muscles. He consistently weighed above 250 lbs by the way. Arreola is a fat journeyman. Godfrey had also longer reach than Arreola.
That must have been a compelling newspaper clipping for you to conclude he was Arreola’s size. Stiverne was a top am who gained a title in super heavyweight times. Sharkey was one of the lesser heavyweight champions at a time when they were the size of current 175 fighters. If Arreola was a journeymen for losing to three champions in his prime and nobody else, I’m not sure what that makes a double digit loss column guy like Godfrey.
He was though... he was only half inch shorter, had longer reach and both fought consistently above 250 lbs while being not in great shape. Who did he beat to gain the title...? Yeah and he beat plenty of big guys, including ones as big or bigger than Arreola. Godfrey was also a journeyman, but he wasn't worse than Arreola. About number of losses - Godfrey fought 120 times, losing 21 of them (17.5%). Arreola fought 45 times, losing 6 of them (13.3%). Given that Arreola isn't retired yet and he'll take more losses at the end of his career, I don't find his record any more impressive.
Really? Reports I've read have described Godfrey as making a "miserable showing" and the bout as "disappointing" and a "fiasco".
Stiverne beat a perennial contender who he was narrowly favored to beat. You must really not like how Godfrey had double digit loses, many to nobodies, if you're gonna twist it and start pulling up Arreola's past prime loses to champions and contenders. Sharkey never beat any big guys who were aggressive and solid like Chris.
