NFL Offseason - Every year, we here at Football Outsiders do our best to accurately forecast the upcoming season. We run thousands of simulations taking into account major offseason personnel changes, players returning from injury, potential development from draft picks, continuity on the offensive line, and numerous other variables in an attempt to provide the best predictions out there.
Considering how difficult predicting the future can be, 2021 went quite well. There was a .74 correlation between our mean projected wins and teams' actual win totals, and a .73 correlation between our projected DVOA and teams' actual DVOA.
