Faith begins when reason ends. You get to the outer limits of your rational tether and then you take that big leap. It's not necessarily a bad thing: Belief is central to sports. History is filled with stories of those who believed in themselves, thereby achieving great things. There's also a rich trove of "outside-the-box" thinkers who are rewarded when they defy conventional wisdom and mainstream opinion to do things differently, whether in terms of tactical innovation or recruitment approach.
Then again, relying on faith more than reason can also amount to a whole lot of smoke and mirrors.
