Stated by ex-marine giants who would logically have no idea Oden was part of the Roger Pirates and have absolutely no idea how strong Oden was when he died, seeing as Oden didn't even have ACoC when he was a WB pirate.
Furthermore, the marines believe Oden was only a WB commander and again, these giants were ex-marines trapped at Enies Lobby for decades.
So no, Oden is not included in this statement and there is zero evidence suggesting he is. Furthermore, even if he was (he isn't), it would be referring to when he was a pirate, not when he was in his prime. You can choose to think Gaban > Oden, but that's your opinion and cannot be presented as fact.
