Not every state issues NFHS Manuals even if they tend to follow those mechanics pretty closely. (Illinois doesnât issue this Manual (per JRut). Georgia doesnât use FED mechanics. Etc.)
Basketball mechanics are relatively simple; thereâs not a ton of variation in the basics, which is different from football where states tend to differ from the NF more frequently and do things âtheir own way,â necessitating the use of manuals more so. It is much easier to, for example, mechanically go from high school to college or one state to another in basketball than it is in football.
