The question the TS proposed: how good was Akiyama? I said, ‘decent, but not champ material’. You thought otherwise, listing organizations he wouldn’t have been champ in, really.
We’re going in circles, listing fantasy match-ups. Alright. It’s fun to go back in order to think about what would’ve happened. I think he wouldve lost most of those fights, style differences and all, whereas you think he’d do a bit better. The easier question would be: which top ten welterweights does Akiyama beat from 2005 to 2012?
I brought up LeBanner because historically — including kickboxers better than Jerome — K-1 guys have been brought in to be feasted upon. He took Jerome down, Jerome got right back up, and then brawling Akiyama got KO’d. I get the weight differential, inexperience, etc., yet I think it’s an interesting fight, for it shows weaknesses that he’d never fix.
The thing is, Akiyama’s career is all but over. We watched him fight for many years. The fight footage is out there and the records exist. A lot of brawling, some good trips, never could beat mid-card UFC guys. His biggest win is Melvin. His career was a C: big name, made money (drawing power does matter), had good fights; yet he never did anything in the majors (outside of the tourney win). Not sure what else to add. He had some skills. I don’t dislike him as a fighter or person. Just answering the OP.
Edit:
To answer the TS question about potential. Akiyama didn’t underachieve. He was never going to be a perennial top five fighter at welterweight or middle.
