NFL free agency begins with the legal negotiation window at noon ET on Monday. Players can officially sign with new teams after 4 p.m. ET on Wednesday, which is the start of the new league year.
There has already been plenty of action this offseason, however. The franchise tag window closed at 4 p.m. ET on Tuesday, and two players (Bengals receiver Tee Higgins and Chiefs guard Trey Smith) were tagged. Teams can also agree to terms on trades, as we saw with the Steelers' deal for DK Metcalf and the Raiders' move for Geno Smith.
