Also, seeing Borsalino do the Nika dance might move him above Fujitora and Aokiji for me. Already love the stoner uncle gimmick, but knowing he's a Nika stan might clarify what Saturn meant by "I know why you're down".
Perhaps his heart wasn't into the fight not solely due his connections with Bonney, Sentomaru, Kuma, and Vegapunk, but also from his fondness for Nika developed during their time together.
