Johnson participated in the Australian NBL's Next Stars program in 2023-24 and averaged 2.9 points in 7.7 minutes with the Illawarra Hawks. The 6-foot-4 guard is clearly raw and is years away from being a reliable contributor for the Bucks, so his fantasy upside is almost non-existent across all formats. He might be a player worth stashing in dynasty formats, but when it comes to standard leagues, he's not worth drafting under any scenario since he's buried in the depth chart of a contending team filled with veteran players in their roster.
