The year 2025 is characterized by significant off-field controversies in sports, including gambling scandals and doping violations. The NBA banned Jontay Porter for life due to game manipulation for prop bets, following earlier NFL and college athlete gambling breaches. Tennis player Jannik Sinner received a three-month ban for a doping violation. These incidents highlight growing concerns about integrity, transparency, and credibility within modern sports, exacerbated by the booming betting industry.
