If there is a defining aspect ...

If there is a defining aspect of UNC women's soccer, and its success, it is what we call the competitive cauldron. It is the pinnacle of our program. The great part about the cauldron is that it fosters a quality we can all possess. It isn't a talent we are born with. Competitive drive is not governed by innate ability, but by self-discipline and desire

You can never be fit enough for this game.

One of the most unfortunate things I see when identifying youth players is the girl who is told over the years how great she is. By the time she's a high school freshman, she starts to believe it. By her senior year, she's fizzled out. Then there's her counterpart: the girl waiting in the wings who quietly and with determination decides she's going to make something of herself. Invariably, this humble, hardworking girl is the one who becomes the real player.
