Michael Moorer has turned pro in 1968 as a heavyweight. As a manager it's your job to control Moorer's career. In other words you've got to guide moorer and maximize profit and the end goal is to get to the title and reign as the champion. Obviously this will be very difficult to do in the 70s with some of the greatest legends boxing has known. But a high quality southpaw like Moorer gives you a lot to work with IMO.
Avoid fighters like Foreman, Frazier, Shavers, Lyle, any dangerous punchers as Moorer had a bit of a shaky chin at Heavyweight His best shot at picking up a belt is to fight Norton in 1978 or beating a faded Ali after 1975. Fighters I think Moorer would match up well against Ellis, Patterson, Quarry, Young.
