Hall of Fame coach and current Dolphins president Bill Parcells from Charlie Jones' 1997 What Makes Winners Win:
Confidence is only born out of one thing -- demonstrated ability. It is not born of anything else. You cannot dream up confidence. You cannot fabricate it. You cannot wish it. You have to accomplish it. Macho or swaggering kinds of confidence many times are just a coverup for lack of confidence. I think that genuine confidence is what you really seek for your team and your individual players. That only comes from demonstrated ability.
