The rocky port incident was a huge thing
if Ochoku was that weak Bb would have steamrolled the place and wouldn’t really need the Coby/Law diversion
Pretty sure Ochoku had all pirates of the island on his side, pretty much big shoots too.
What Teach probably mean with it that Koby and Law made it easier for him to get Ochaku.
Let be honest, I see Ochaku stronger than Marco(by hype) but he got probably got wrecked by Teach and his crew...
Even someone as Magellan got wrecked by a none Gura Teach+Blackbeard pirates and we speak about Teach who had two dfs, defeated Marco and was a Yonkou.
At best Ochaku pushed him to mid diff.
