CST80 is right I wouldn't get your hopes up on any light heavyweight in th world when Kovalev and Beterbiev are at the top and Mekhonstev and Gvozdyk are coming up
KO'ing any version of Campillo in 1 round is impressive However you must know deep down that he has absolutely no chance against Kovalev or Beterbiev hi:
PBC are usually fairly good about putting their stuff up on YT, I guiess even they're too embarrassed to put up the mismatches from the past two days in their entirety.
Browne is very fast, but he usually only fights like that for the first two rounds. If he can't take you out in those two rounds he starts slowing down. Mekhontsev is not looking too good as a pro so far imo. We still can't count him out ig, but I'm not so sure about him. I would say Bivol is better than Mekhontsev.
manfred does have some gold you should check out my 2012 olympians rating their pro prospects, id marcus browne rated as a C- and some guy complained said he should have been higher
