My point is that when most people talk about the strength of the Roger Pirates, you can easily assume that Oden isn't taken into account.
Every other member has had decades of relevance and countless engagements with the Rock Pirates, WB Pirates, Marines etc... while Oden spent a single year with them. Yes, they reached Raftel during that year but to the world at large, Oden as an individual might as well not have been there since his contribution was imperceptible.
Think about it, Akainu simply refered to him as a short lived WB commander, the bulk of Marine officers don't know he existed and even someone like Sengoku (who was already high in the hierarchy at the time) would have no way to access his strength considering no major confrontation happened in the year Oden spent with Roger. To him, he is simply an intriguing samurai that sailed with the crew during their last voyage.
The average Joe talking about how strong the members of the Roger Pirates were will never bring up Oden because of the simple fact that they do not know the first thing about him.
