Drafting an NFL quarterback is risky business, and the lesson of Druckenmiller’s story and others like it is that no one truly knows which players will succeed in the pros. Even the brightest GMs and coaches can whiff badly: By nearly any measure, fewer than 50 percent of passers drafted in the first round wind up as quality NFL starters, while fewer than 20 percent become stars.
