Using the Official World Golf Ranking, it's easy to quantify which players had good years and which players had, well, not-so-good years.
Jordan Spieth was among the former group in 2021, snapping a lengthy victory drought and returning to the upper echelon of the men's game. On the other end, players such as Webb Simpson and Matt Kuchar dropped significantly. Tiger Woods also experienced a sharp world-rankings fall, though his decline was due to a serious car accident in February that required extensive surgery to his right leg and kept him from logging an official world-ranked tournament round all year.
