From this list it’s between Bam and Bivol. Bivol was an underdog and beat the P4P king at the time but he was also the bigger man.
Bam moved up two divisions this year and took on a killer in his second fight though the killer was coming off a long inactive stretch. Gonna say Bam because we’ve seen Canelo being outboxed before but we haven’t seen SSR stopped before except for his first 2 fights that are not relevant anymore. Estrada and Choc were hitting him with some hard shots too but didn’t even come close to stopping him.
I don’t think Leigh Wood belongs here, dude looked clueless most of the fight against Conlan who’s probably an Euro level dude.
Beterbiev, Haney, Shakur, Spence, Inoue, Chocolatito, Cordina all deserve a mention before Wood imo
