You think Kobe was mediocre defensively in 08 and 09? Any drapm source i know has him as a positive there, and we know he could amp it up in the playoffs as needed.
This is one of my more stuffy opinions, but I look at film first to analyze defense and then advanced stats, because I don't think the stats have progressed yet to the point where they mean enough to provide a starting point. Every defensive advanced stat I've ever seen is full of weirdness and anomalies; many are very good over a long period of time, but using them as an objective, context-free ranking tool for individual players in individual seasons can be dangerous, and RAPM is no exception. What Hera said about single-year RAPM earlier is really, really true:

If you're interested in delving into why this is true, this goes into it:
https://squared2020.com/2018/12/24/regularized-adjusted-plus-minus-part-iii-what-had-really-happened-was/Kobe's 14-year DRAPM as per here is -0.9:
https://public.tableau.com/views/14YearRAPM/14YearRAPM?:embed=y&:showVizHome=no Now, this does cut out some of his better years at the beginning of his career, just because we don't have the +/- from back then, so I'm sure it's dragged down by that and by how awful he was after the injuries. BUT, I still think it's unlikely that he's better than okay by 08/09 given that number.
I would look at the PIPM trend, since we have full PIPM for most of Kobe's career rather than just the box prior, but for some reason I'm getting an access denied message when I try to look at the player finder - is anyone else having this problem?
On film, Kobe's defense is just not that impressive to me. He's not totally awful, but he's not great either. He gets blown by a LOT, and his attention level is inconsistent. He can turn things up on an individual-possession basis, sure, but I think he does this less often than his reputation indicates. Better than Nash? Absolutely. Meaningfully positive? I'm not sure.
edit - even if you
do look at individual seasons, this has him hovering around +0.5 in the regular season (which is what I think of as "just okay") in and around the years mentioned, with playoffs seeming essentially random:
