NFL free agency began on Monday with the legal negotiating window, and we've already seen a ton of offseason action -- including a few surprising moves. Sam Darnold, Justin Fields, DK Metcalf, Davante Adams, Josh Sweat, Milton Williams and D.J. Reed are among the biggest names who have changed teams via free agent signings and trades.
ESPN analytics writer Seth Walder is grading the biggest signings and trades of the offseason, putting each deal into perspective for teams and players. To determine each grade, Walder is evaluating moves based on multiple factors, including on-field impact, salary cap implications, compensation, player value/age and the context of a team's short- and long-term outlooks. How large is the effect of this decision, and how sure are we it's a good or bad choice? How does this affect a team's chance to win the Super Bowl, either this season or in the future?
Follow along as Walder evaluates and grades each move, with the most recent grades at the top. We've already tackled more than 50 deals.
