Since they were a made for TV band they "cast" them to play their instruments. Davey Jones was the only one who knew how to play the drums, but the producers thought that being behind the kit would emphasize his short stature and he wouldn't be seen. So they moved Dolenz behind the kit and put Davey out as the front man. Tork was a better guitarist than Nesmith, and Nesmith had played bass before, but the producers switched that up as well and made Tork the bassist. Based on abilities, the lineup would have been Jones on drums, Tork playing lead guitar, Nesmith on bass, and Dolenz as the lead singer and front man.
