|This guy has raditude.|
We're pretty sure Gareth Edward's choice of Admiral Raddus to lead the Rebel fleet in Rogue One had anything to do with his name or that the Mon Calamari General would be so actually rad a character.
Or maybe they got the name joke. Either way, Raddus was a key minor character from the movie. It's quite possible that Raddus will overtake Admiral Ackbar in the popularity stakes over time. Hey! Calm down, nothing will ever beat Ackbar's 'it's a trap' quote from Jedi.
