That is probably because Lomachenko didn't duck anyone, unlike Duck Runhugger Jr. who made a career out of cherry picking and ducking the best fighters in their primes.
Floyd was grossly underrated p4p by the experts for so long. Ring had freaking Stevie Johnston ahead of him several fights into his championship reign, Corrales higher before they fought and Floyd only 7th, and after he beat Corrales barely budged him up, had Mosley number 1 and Barrera ahead of Floyd. I had him number 2 below RJJ in 1999, and I was proved right within a couple years when so many supposedly p4p greater guys quickly took bad Ls.
Sorry Mr Nuthugger but Mayweather and Crawford do NOT lose to the likes of Orlando Salido. They.Just.Don't. However, all is not lost. Your hero could redeem himself. All he has to do is go up to 140lbs and beat Terrance Crawford...
