Is Being Humble Good For BJJ?

Is BJJ built on Humility or fought and won by Ego? Even though much of what is encouraged in the world of BJJ is to be humble and respectful, so much of the success we see in the competitive arena is brash shows of Ego. Trash talk, people beating their chests and making fun of other competitors does show much humility at all. The key question is- does be humble help your BJJ?
It is a great quality as human to be modest but this is not necessarily going to help you improve at BJJ. The level of self belief and ego it takes to over come all the challenges BJJ throws at you in order to be great has little to do with Humility. Can Ego and Humility coexist or are they counter points? Let us know what you think in the Comments.
