Remember Jack got out of that pretty much completely unscathed after already suffering injuries by attacking a convoy of Marine ships with Sengoku, Tsuru and I think Fujitora all present. And before that he was fighting Nekomamushi and Inurashi consecuatively for five days and nights.

From whats been shown of the Headliners it seems like these are the captains of Kaido's subordinate crews and they range in strength. Sheepshead, Holdem and Speed are likely pirates of similar level to Caribou who joined Kaido for the power his name give them.

Drake, Hawkins and Apoo are probably on the a similar level to Luffy and Law but saw that they couldn't beat the guy and so joined him instead.

Basically the strength level goes

- Kaido

- Jack

- Drake, Hawkins, Apoo

- Speed, Holdem, Sheepshead
