NOTHING IN THE world of analytics agitates folks quite like the question of whether some athletes can turn up their game in critical situations. Traditionalists believe Tom Brady has clutch in his DNA, statheads think they can simulate clutch by crunching numbers, and frankly, I'm tired of their talking past each other. So for this column, I'm trying something different. Instead of building toward one inexorable conclusion, I'll show what we know about clutch, playing no favorites. Trust me, by the end of this, we'll find some common ground.
