Leicester City Win the Premier League (2016)

Leicester City's 2016 Premier League triumph defied 5,000-to-1 pre-season odds, the longest in professional sports history for a title. The Foxes finished 10 points ahead of second-place Arsenal, a gap wider than the average underdog champion's margin. This upset outperforms #7 Muhammad Ali's phantom punch in cultural impact, inspiring a 2016 film. Their 81.6% win rate at home exceeded the typical top-tier club's 70% average, with Jamie Vardy scoring 24 goals—a 33% increase over his prior season's total.
