It's hard to become a head coach in the NFL. It's even harder to remain a head coach in the NFL.Three guys who earnedsuchjobs just two years ago Chip Kelly, Ben McAdoo and Mike Mularkey are no longer in theirpositions. Meanwhile, Doug Pederson, another 2016 hire, just coached the Eagles to victory in Super Bowl 52.Those who were hired last year set a higher overall standard. Sean McVay (Rams), Sean McDermott (Bills) and Doug Marrone (Jaguars) helped end three teams'long playoff droughts. Kyle Shanahan (49ers) and Anthony Lynn (Chargers) both had promising finishes to the 2017 season. Vance Joseph (Broncos) got a reprieve and a chanceto live up to his high expectations.The league is welcoming seven new hires in 2018. Four are first-time NFL head coaches.MORE: NFL offseason schedule There's one obvious standout:the man returning to the Raiders with a ring on his hand and redemption on his mind.Consideringpotential immediate impactand the prospects of long-term succe Jaylon Smith Jersey s, here's ranking a strongcla s of new coaches, from solid in Tenne see to spectacular in Oakland.7. Mike Vrabel, TitansAge: 42Previous position: Texans defensive coordinatorTenne see in 2017got to the playoffs after nine long seasons and won its wild-card gamewith Mularkey, but it decided to gohunting for a big name. It ends up with a rising young starat the cost of losing a savvy defensive coordinator, and causing yet another staff change for Marcus Mariota.Vrabel has had a terrific trajectory as an a sistant, and his winning history as a player will relate well to a young team. In a suddenly tougher AFC South, however, the rookie is facing a big challenge to improve from 9-7 rather than fading early. Vrabel made some strong staff Dak Prescott Women Navy Jersey hires, getting former Ravens defensive coordinator Dean Pees to come out of brief retirement and convincingnew offensive coordinator Matt LaFleur to leave the Rams' Jared Goff for Mariota.6. Pat Shurmur, GiantsAge: 52Previous position: Vikings offensive coordinatorShurmur's first head-coaching gig came with the Browns, so hedidn't have much of a fighting shot there. Nowhe inherits a team with a veteran-yet-fading QB inEli Manning; a teamthat was in the playoffs on the strength of great defense just two seasons ago.Shurmur has fared fine as an OC, but handlingthe pre sure of coaching the highest-profile, biggest-market team can be an early make-or-break scenario. Will he be the right guy to re-mold Manning and diffuse the dramaled by Odell Beckham Jr.?Going from the organized ways of the Vikings to the post-chaos cleanup of the Giants is bound to meet mixed-at-best early results.5. Steve Wilks, CardinalsAge: 48Previous position: Panthers defensive coordinatorWliks is bringing the feel of Carolina to Arizona, much like his predece sor McDermott did in Buffalo. It was smart for the Cardinals to go defensive-minded for Bruce Arians'replacement with an offense already in major transition thanks to Carson Palmer's retirementand David Johnson's impending return.Wilks can get more out of the team's established, strong defensive unit, from Chandler Jones off the edge to Patrick Peterson on the corner. Seeing what Cam Newton did for the Panthers, Wilks isalsolooking like an accepting coach for a young, dual-threat QB (hello, Lamar Jackson?) and can stayout of the way of his OC (hello, Mike McCoy?).4. Matt Patricia, LionsAge: 43Previous Dez Bryant Jersey position: Patriots defensive coordinatorPatricia reunites with former New England executive Bob Quinn, now Detroit's fine general manager. With Matthew Stafford in a groove, there wasno reason to replace offensive coordinator Jim Bob Cooter. The Lions' defensive talent needs to be maximized, and astrong secondary is afamiliar foundation for Patricia and his seasoned coordinator, Paul Pasqualoni.This is still a team that made the playoffs in two of the past four yearsand was on the brink of making it in 2017. Patricia's personality is a better fit in the NFC North than it would have been in the NFC East with the Giants.Patriciacan have quick succe s, as the hard part of findinga franchise QB is out of the way.3. Frank Reich, ColtsAge: 56Previous position: Eagles offensive coordinatorThe Colts mighthave dodged a big bullet with the Josh McDanielsme s. They instead land the winning offensive coordinator of Super Bowl 52, and Reich already looks like the right, better move.Reich started his pro coaching career in Indianapolis. He will bring respect back to the organization and also get plenty of it from his players. That's before getting into the fact that he'll have a strong influence on Andrew Luck after his recent work with Philip Rivers, Carson Wentz and Nick Foles.This isn'tjusta rebound second choice for the Colts. Demarcus Lawrence Jersey This isa home run.IYER: Reich hire a luxury for Colts2. Matt Nagy, BearsAge: 39Previous position: Chiefs offensive coordinatorNagy is trying to follow Pederson in moving on tohave top-level NFC succe s with a talented QB taken No. 2 overall in the draft. He is the perfect guy to raise Mitchell Trubisky to the next level with his pa sing skill set and athleticism.Nagy also had the foresight to keep Vic Fangio in charge of the defenseand accelerate the offensive principles with Mark Helfrich. Nagyalready has looked the partand talked the part of having many good years in Chicago.1.Jon Gruden, RaidersAge: 54Previous position: "Monday Night Football" analystWill Gruden rediscover themagic that turnedthe Raiders intoAFC championsand raised the Bucs to Super Bowl champions? Ten years is a long time away from the game, but Gruden picked a good time to return, with Derek Carr and Khaili Mack as the ideal leadersonly a season removed fromearningthe team's first playoff berth since 2002.Gruden has an all-star staff and still has a genius football mind. He will get the results andreturn to his status as a coaching superstar.... Just in time for Dez Bryant Navy Game Jersey the glimmer of Las Vegas.
