ALAMEDA Austin Seibert Jersey , Calif. (AP)The Oakland Raiders added some needed help at cornerback, agreeing to contracts with free agents Rashaan Melvin and Shareece Wright on Friday.A person familiar with the move said Melvin got a one-year, $6.5 million contract. The person spoke on condition of anonymity because the terms were not announced. ESPN first reported the signing.Wright announced his plans to join the Raiders on his Instagram account .The Raiders also added some depth to the defensive line with former San Francisco 49er Tank Carradine saying he will stay in the Bay Area and join Oakland.Oakland has lost the three cornerbacks who played the most last season, releasing Sean Smith and David Amerson, and losing TJ Carrie to Cleveland in free agency. The Raiders were looking for proven players to team with last year’s first-round pick Gareon Conley, and they hope Melvin and Wright can fill that role.”I felt like it was a place I could call home,” Melvin said. ”I can relate to these guys. They have big plans for me, big plans for the organization. I was born to be a part of something special. That’s happening in Oakland.”The 28-year-old Melvin had three interceptions and 13 passes defensed in 10 games last year for Indianapolis. He limited opposing passers to a 67.2 passer rating when getting targeted last season, according to SportRadar, and should immediately step into a starting role for the Raiders.After spending time with Tampa Bay, Miami Trysten Hill Jersey , Baltimore and New England, Melvin has thrived the past two seasons with the Colts.”I’ve been cut four times. I’ve been in four different locker rooms, and I was able to gain my teammates’ trust, my coaches’ trust and the organization’s trust as well,” he said. ”My confidence just grows over time. There’s not a lot of players that can say they’ve been cut four times and end up in a situation where I’m at today. Like I said, it’s perfect timing. My work ethic, my style of play and the way I approach the game and the way I approach my job, my business, it speaks for itself.”Wright, who turns 31 next month, has played seven seasons with the Chargers Connor McGovern Jersey , Ravens and Bills. He spent last season in Buffalo where he had one interception and five passes defensed in 12 games. Wright has experience playing both outside and in the slot.Carradine played 44 games over four seasons with the 49ers, recording 5sacks.These additions are the latest move to overhaul a defense that struggled mightily during a six-win season in 2017 that led to the midseason firing of coordinator Ken Norton Jr. and cost head coach Jack Del Rio his job after the season.New coach Jon Gruden and coordinator Paul Guenther are looking to make major improvements on a unit that had holes at all three levels and struggled both against the pass and run despite the presence of star defensive end Khalil Mack.A year after signing no prominent defensive free agents, the Raiders have already added several new potential starters in free agency, with linebacker Tahir Whitehead and safety Marcus Gilchrist having already signed deals this week.”You could just feel the energy in the building in what everyone feels like is ahead,” Gilchrist said. ”Obviously, you know the offensive weapons that are here. You always start with the quarterback and there’s a great quarterback here. With that in mind. You have the pass rush here and a bunch of young players that have a bunch of upside. It’s exciting to be around and see and be here firsthand.”The Raiders also signed free-agent long snapper Andrew DePaola – who got a four-year, $4.27 million contract with $875,000 guaranteed – and punter Colby Wadman.DePaola replaces longtime long snapper Jon Condo, whom the Raiders decided not to bring back for a 12th season.DePaola spent last season with Chicago after playing his first three years with Tampa Bay. He has played all 64 games the past four years.Wadman played college ball at UC Davis and had tryouts last season with Oakland and Indianapolis.— Leonard Fournette‘s season-long struggles proved costly for his position coach.The Jacksonville Jaguars fired running backs coach Tyrone Wheatley and three more assistants Monday night, according to a person familiar with the situation. The person spoke to The Associated Press on the condition of anonymity and said offensive line coach Pat Flaherty, secondary coach Perry Fewell and defensive line coach Marion Hobby also were let go one day after the season finale.Wheatley’s dismissal was the least surprising. It came one day after Fournette and T.J. Yeldon were sharply criticized for being disengaged from coaches and teammates during the 20-3 loss at Houston.Coughlin ripped both players for being “disrespectful” and “selfish.” He said “their behavior was unbecoming of a professional football player.”More Jacksonville Jaguars newsJaguars expect DE Yannick Ngakoue’s holdout to be short-livedJaguars rookie safety Zedrick Woods submits retirement paperworkJalen Ramsey says Jaguars don’t plan to give him contract extension this seasonJaguars sign former UCF running back Taj McGowan for added depthJaguars QB Nick Foles to miss OTAs for undisclosed ‘personal reason’Fournette has missed 11 games in two seasons Foster Moreau Jersey , including two because of suspensions, and has shown little interest in being a good professional. Yeldon, a pending free agent, barely played down the stretch. Jacksonville also traded a fifth-round pick for Carlos Hyde, who ran for 189 yards in eight games.All four assistants had been with the team for two seasons.Wheatley’s position group was among the least production in 2018. Fournette was one of the NFL’s biggest disappointments, finishing with 439 yards rushing and five touchdowns while missing eight games.Flaherty’s line was ravaged by injuries, but he also got little out of free-agent guard Andrew Norwell. Fewell’s secondary wasn’t nearly as productive as it was in 2017 and saw veteran safety Barry Church waived late in the season. Hobby’s unit underperformed at several positions, and first-round draft pick Taven Bryan made marginal gains in his rookie year.Coach Doug Marrone also fired offensive coordinator Nathaniel Hackett in late November, meaning he now has five job openings heading into the new year.Marrone said earlier Monday that he didn’t want to make any staff changes based on emotion, adding that he would make sure “it’s for the right reasons and not just a reaction.”
