fast twitch muscle mass vs slow twitch muscle mass. CB is a position where top line speed, quickness, change of direction are all important and benefit from CB having more fast twitch muscle.

Absolutely. Certainly genetics can help folks ... perhaps to help them have predisposition towards having greater ease of developing fast-twitch muscle. However, such muscle can still be developed ... irrespective of such predisposition. Furthermore, as East German women proved back in the 80s (and before), chemical intervention can also impact such muscle development too.
