Some folks don't understand how Competition really works, and they often believe that the most boisterous competitor is a blowhard or braggart, and lacks the skills. The reality is that a little bit of bravado, and psyching yourself up, while detracting the opponent from their own game is actually part of the competition. It turns out that often the competition is won before it starts, because one competitor is able to place doubt in the other competitor's mind. Often it is a game of will, and not only of strength or skill. Indeed I'd like to discuss this with you for a moment if I might.
This isn't to say that everyone who carries on with bravado has the strength of character or the will to win, rather it is to say that such an external projection of strength, power, and energy does have a psychological effect on the other team, the other players, and even the mood of their fans. Now then, I've been in enough competitions in various sports and industries to spot a bluff or fake out when I see it. And there are many who run around blowing smoke up everyone else's but, but when it comes time to perform, they fall flat and come up short.
Whereas, these folks may never get into the winners circle, they attempt to take their glory before the event, they often do cause as a different outcome from this theory that; the best man will win. It is the person with the best mindset, strength of character, and will that has the greater likelihood of winning even if they don't possess superior skills, talent, or sheer brute strength. There've been many psychological studies which confirm this, along with the whole "Psychocybernetics" concept by Maltz back in the 50s.
Further, often it is the belief that helps people achieve and allows those with less interior willpower to perform at their maximum with others on their team. This is of benefit, and also has a lot to do with the home town advantage, as onlookers cheer. If someone tells you you're great, you tend to believe it, and you are more likely to try harder to retain that respect, even if you didn't really deserve it in the first place. This is human nature.
A team which appears intimidating before the competition or match definitely has the advantage, and good and smart coaches know this, and they take that advantage and run with it as hard and as fast as they can. Therefore, it's not just bravado, it actually counts in competition. Indeed I hope you will please consider all this and think on.
