Some call it parity. Others consider it bad football. No matter how it’s viewed, the NFL is providing plenty of close games, thrilling comebacks, big upsets and late-minute heroics. It keeps viewers entertained — or at least tuned in until the end. Five weeks in, 24 games have featured a winning score in the final two minutes of regulation or in overtime. That’s the most through Week 5 in league history. Seven teams did it last week, including Tampa Bay for the fourth time already this season.
