Every year, March Madness brings back a chance to learn. Turns out it's the same lesson every year: Styles makes fights. What it means is this: When two forces meet -- forces with very different assets, ideas, and ways of operating -- anything is possible and, more profound, nothing can be counted on. No doubt, the lesson permeates college basketball's end-of-season tournament because every year teams that have never played each other in the regular season and know scant little about each other, suddenly meet. Teams can watch film and strategize, but it's impossible to accurately estimate how they'll respond to a completely foreign style until they actually meet it. That's when styles make fights. And who wins? Be it in college basketball or business, it's the leader and the team ready to adapt.
