BB is more of a rival to luffy than a straight up enemy
Meanwhile
Koby and BB are on two sides of the law
They have been involved in multiple conflicts against each other either directly or indirectly
And Garp sacrificed himself to save Koby who was kidnapped by blackbeard to leverage his title
If where to believe koby is gonna be a rival to luffy let alone an admiral by the end of the series he needs to do something crazy impressive to prove himself
Taking down bb and saving the world would be pretty impressive

Are you seriously contesting BB vs Luffy in favor of BB vs Coby? Lmao
BB isn't just a rival.
He is the only one who mirrors Luffy in all sense.. from growth to personality to having special df.
They aren't just contending for PK but both of their dreams goes beyond that.
Both have special lineage
And, it's personal. Impel down made it clear.
Ace was captured because of BB.
Garp is captured by BBP.
I don't know why you are inserting Coby when it's not even about him?
