NFL free agency is off and running, and we're keeping track of every major signing, trade and release of the 2021 offseason, with analysis from our NFL Nation reporters and grades from our experts. The new league year began March 17 at 4 p.m. ET, meaning free-agent signings can be made official after that. The first round of the 2021 NFL draft begins April 29 on ESPN.
The Chiefs are attempting in 2021 to become just the fourth franchise to appear in three straight Super Bowls. They couldn't repeat as NFL champions last season, losing in Super Bowl LV to the Tampa Bay Buccaneers 31-9.
