Mumbles is constantly mumbling, hence the name mumbles. Perhaps he is trying to impart some great wisdom, but that seems unlikely due to the fact that he has thus far been too stupid to remove the bandages from around his mouth.

Fumbles has a history of constantly fumbling the ball making him one of the worst players to ever play bloodbowl. His fumbling is due to his pre-un-death occupation of carpentry.

Regardless of the reason fumbles is a popular player.
