✅ The Truth:
Home advantage has been declining for 20 years. In the 2020 COVID season with empty stadiums, home win % dropped to 43.3% (from the usual 46%). The crowd DOES help, but it's smaller than you think — about 3-5% advantage, not the 15-20% people assume.
✅ The Truth:
Multiple studies show "momentum" doesn't exist statistically. A team scoring 3 goals in 10 minutes isn't on a "hot streak" — they're benefiting from variance and opponent collapse. The "hot hand" in basketball is real (confirmed in 2018), but game-level momentum is mostly narrative.
✅ The Truth:
Physical peak varies by position. Goalkeepers peak at 30-33. Strikers peak at 25-27. NBA point guards peak at 27-30. LeBron was elite at 37. Messi won the World Cup at 35. Peak age is not a hard number — it's a range influenced by style, injuries, and fitness.
✅ The Truth:
Not always. The 2017-18 Warriors won with offense (113 points per game). Manchester City won 4 straight PL titles with the best attack, not the best defense. The truth: you need both. But if you have to choose, elite offense beats elite defense in modern sports.
✅ The Truth:
Research shows the correlation between transfer spending and league position is weaker than you'd expect (~0.6 R²). Wolves spent £100M+ and got relegated. Chelsea spent £1B and finished 12th. Money helps, but coaching, culture, and recruitment intelligence matter more.
✅ The Truth:
Most "clutch" performances are small sample sizes and confirmation bias. Jordan's shooting % in the final minute of close games was actually below his career average. The exception: free throw shooting under pressure IS measurably worse (4-7% drop). Choking is real; clutch-ness isn't.
