The Las Vegas Raiders have seen their roster go through a complete overhaul this offseason. As the Raiders look to rebound from their disappointing 6-11 season, Las Vegas has added two more free agents who have experience playing in the playoffs.

The Raiders have signed former Buffalo Bills safety Jaquan Johnson, via ESPN's Adam Schefter. Las Vegas has also signed former San Francisco 49ers defensive end Jordan Willis, per Matt Barrows of The Athletic. While financials of the deals are not yet known, both Johnson and Willis will be signing one-year contracts.

Johnson has spent his entire four-year NFL career with the Bills. While he has just four starts to his name, Johnson has appeared in 60 games overall. The safety has made 58 tackles, two passes defended and two interceptions.

Unlike Johnson, Willis has bounced around the league since joining the NFL in 2017. However, he has been with the 49ers for just over two full seasons. In 69 games, Willis has made 92 tackles, 10.5 sacks and three forced fumbles.

While Las Vegas' biggest free agent splash was their signing of Jimmy Garoppolo, it was clear that the Raiders were in need of some serious defensive help. The team finished 28th in total defense this past season, allowing 365.6 yards per game.

Neither Jaquan Johnson nor Jordan Willis will suddenly make the Raiders defensive juggernauts. However, they both have plenty of experience playing at the NFL level. As the Raiders trim their roster down before the start of next season, both Johnson and Willis will be looking to prove why they deserve a spot.
