The Philadelphia Eagles are rewarding head coach Doug Pederson and general manager Howie Roseman with contract extensions through the 2022 season Justin Jones Color Rush Jersey , per ESPN's Adam Schefter.Eagles announced matching contract extensions through 2022 for GM Howie Roseman and HC Doug Pederson.— Adam Schefter (@AdamSchefter) August 5, 2018Roseman and Pederson constructed a dominant Eagles team that won their first Super Bowl in franchise history last season, defeating the New England Patriots 41-33. And with the team built to compete for several more championships in the immediate future, Pederson and Roseman were more than deserving of their extensions.Pederson's NFL coaching career began in 2009, when the Eagles hired him as their offensive quality control coach. Pederson was moved to quarterbacks coach in 2011, a role he would keep for two years.The Eagles then fired Andy Reid Josh Gordon Browns Jersey , who became the new head coach of the Kansas City Chiefs in 2013. Reid brought Pederson in to serve as his offensive coordinator. But after Philly fired Chip Kelly, Pederson was brought back to Philadelphia as their new head coach for the 2016 season.As for Roseman, he became the Eagles' general manager for the 2010 season, and kept the job until 2014. However, the Eagles stripped him of the gig and moved Roseman to Executive VP of Football Operations, though he was later moved back to the general manager聽job. Roseman has had incredible success in drafting Kyle Freeland Colorado Rockies Jersey , trading and free agency since taking over in the front office. He made a bold decision to trade up and land quarterback Carson Wentz with the second overall pick in 2016. Besides that, Roseman brought back quarterback Nick Foles, who wound up leading the team to a Super Bowl 52 championship.The Eagles have a dynamic core led by Wentz, Foles, Alshon Jeffery, Jay Ajayi Cheap Anthony Miller Jersey , Fletcher Cox and Brandon Graham. After decades of misery, this team came through to win its very first Super Bowl. Thus, the long-term extensions for both Roseman and Peterson were well-deserved. The Miami Dolphins are looking to upgrade their secondary before the start of the regular season, reporting "actively and aggressively" targeting a starting cornerback, according to Omar Kelly of the Sun-Sentinel.While Xavien Howard and Bobby McCain have fared well, the team apparently hasn't liked what it has seen from the rest of its corners.Miami finished last season ranked 16th in the NFL against the pass but are apparently hoping for much better numbers in 2018.Howard was the team's top option at cornerback last season Matt Adams Jersey , starting 16 games while tallying a team-high four interceptions.聽McCain and Cordrea Tankersley rotated at the other corner spots to limited success, but they each returned in 2018.聽Depth was already a problem last season, but the聽Dolphins chose not to re-sign veteran Alterraun Verner. Although the organization used its first-round pick on versatile defender Minkah Fitzpatrick, the Alabama product has been used as a safety instead of at corner.Sixth-round pick Cornell Armstrong out of Southern Miss also has a chance to make an impact but the team clearly sees a need for more help at the position.Josina Anderson聽of ESPN reported the Dolphins hosted free-agent cornerback Bashaud Breeland on Sunday, but no deal has been reached..
