Unfortunately, as good as KAT is, I think they really need to work on their team defense to get into the playoffs in a challenging West. They are near the bottom in most of the team defense categories - see here: https://www.lineups.com/nba/team-rankings/defense. This might take a coaching change, but we already saw that the Thibs method didn't work well with KAT, so maybe not something as drastic as that.
