We're now through the first three days of NFL free agency, with the legal tampering period in the rearview mirror and the new league year officially in swing. We've been breaking things down from every conceivable angle all week here at CBSSports.

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, Joey Bosa and D.J. Reed are among the biggest names who have changed teams via free agent signings and trades.

Hargrave has agreed to a contract with the Vikings, Tom Pelissero of NFL Network reports. Minnesota already has a deal in place with Jonathan Allen, but the team’s spending spree at the line of scrimmage is set to continue. The Vikings’ efforts to shore up their offensive line has included agreements with former Colts Ryan Kelly and Will Fries.
