Well, I would agree with this if Mingo was cautious of Kuzan since the beginning but he pretty much ignored his previous warning and tried to kill Smoker in front of Kuzan. Only after the warning shot, Mingo reconsidered his decision and left Punk Hazard.
But yeah, the performance of Mingo and Cracker is very clear after this cover story... or Wano. Doffy is significantly stronger than Cracker.
