2018 Fantasy Football Rookie Rankings: Dynasty
Saquon Barkley, RB, Giants
Saquon Barkley is more than just an ordinary running back; he'll be the centerpiece of the Giants' offense, much like Marshall Faulk was for the "Greatest Show on Turf" Rams teams. Barkley should be a first-round fantasy pick this year in all formats.
Rashaad Penny, RB, Seahawks
Rashaad Penny, chosen 27th overall in the 2018 NFL Draft, will be a three-down back for the Seahawks, according to Pete Carroll. That's obviously great news for Penny's outlook, but the bad news is that he'll have horrible blocking in front of him. Penny is not very talented either, so it's hard to like his long-term outlook.
Sony Michel, RB, Georgia
Bill Belichick tends to use a million running backs, but given that he spent a first-round pick on Sony Michel, he obviously has big plans for the 31st-overall selection. Michel should be able to function as Dion Lewis' replacement in New England's offense. The downside from a dynasty perspective is that Michel has some injury complications that could cause him to have a shortened career.
Nick Chubb, RB, Browns
The Browns spent a high second-round pick on Nick Chubb. Carlos Hyde stands in his way this year, and I don't expect Chubb to pass him on the depth chart, barring injury. Fortunately for Chubb, Hyde has been very injury-prone throughout his career, so he could get some starts in the second half of the season. He could be the starter heading into 2019.
Kerryon Johnson, RB, Lions
Kerryon Johnson shouldn't have much of a problem bypassing the disappointing Ameer Abdullah on the roster. Johnson is a great fit for Detroit's offense, as he'll catch lots of Matthew Stafford's short passes. This obviously makes him more appealing in PPR leagues.
Ronald Jones, RB, Buccaneers
The Buccaneers lacked talent in the backfield heading into the 2018 NFL Draft, so the only person who can prevent Ronald Jones from thriving this year is Jones himself. I worry about the Tampa party lifestyle getting to Jones, as it has to many young Buccaneers over the years.
Derrius Guice, RB, Redskins
Derrius Guice fell in the 2018 NFL Draft because of character concerns. He even got into a shouting match with members of the Eagles' organization on his top-30 visit to Philadelphia. Guice is very talented, and he's the best pure runner on the Redskins' roster, but I wonder if his attitude will prevent him from becoming the player he should be.
D.J. Moore, WR, Panthers
The Panthers lacked a No. 1 receiver heading into the 2018 NFL Draft, but now they have one. Moore, taken 24th overall, was getting consideration from two teams picking in the teens, so they obviously liked his talent. I'm sure Cam Newton will as well.
Calvin Ridley, WR, Falcons
Calvin Ridley is a precise route-runner who should be able to integrate into an NFL offense quite easily, thanks to the superior coaching he received at Alabama. I don't think I'd draft Ridley before the late rounds, but I could see him ascending into WR2 status if Julio Jones were to suffer an injury. Ridley has a strong long-term outlook, as Matt Ryan should be his quarterback for most of his career.
Michael Gallup, WR, Cowboys
The Cowboys didn't really have any viable starting receivers on their roster heading into the 2018 NFL Draft - Allen Hurns doesn't count - so Michael Gallup should be able to quickly take hold of a starting job.
Royce Freeman, RB, Broncos
Royce Freeman doesn't have much competition. With C.J. Anderson gone, the Broncos didn't really have any viable running backs. Of course, this assumes that Freeman won't be useless himself, so he's no guarantee. The opportunity will be there for him, however.
D.J. Chark, WR, Jaguars
The Jaguars lost their top receiver, Allen Robinson, to free agency. D.J. Chark gets to compete against some mediocre talents at receiver, and he should be able to move up the depth chart quickly. Unfortunately, Blake Bortles' incompetence will prevent Chark from doing great things. Hopefully he's replaced soon.
Dante Pettis, WR, 49ers
It's difficult to trust rookie receivers, and Dante Pettis has a couple of solid players ahead of him on the depth chart in Pierre Garcon and Marquise Goodwin. That said, his long-term outlook appears bright because of Jimmy Garoppolo.
Christian Kirk, WR, Cardinals
Christian Kirk was once viewed as a first-round prospect, but he fell to the middle of the second frame. He should do well in the long term, but he might have a rookie quarterback throwing to him for most of 2018.
Mike Gesicki, TE, Dolphins
I'm usually not a fan of drafting rookie tight ends, but the Dolphins didn't have a tight end on their roster prior to selecting the athletic Mike Gesicki in the second round, so he'll start right away.
Hayden Hurst, TE, Ravens
Hayden Hurst will need to bypass Ben Watson, who is still a functional player at this stage of his career. If Hurst can do this, he could come close to TE1 range, so expect good things from him in 2019 and beyond.
Courtland Sutton, WR, Broncos
Courtland Sutton won't have an impact this year unless either Demaryius Thomas or Emmanuel Sanders goes down with an injury, which doesn't sound implausible. It's likely either Thomas or Sanders will be gone after 2018, making Sutton's outlook bright for 2019 and beyond.
Dallas Goedert, TE, Eagles
The highly athletic Dallas Goedert will replace Trey Burton in Philadelphia's offense. Zach Ertz is standing in his way as far as long-term production.
Antonio Callaway, WR, Browns
Antonio Callaway has some major off-the-field problems, but he's also supremely talented. If he stays out of trouble, he could become a big-time producer for the Browns.
Jordan Akins, TE, Texans
I'm not a fan of fantasy rookie tight ends, but Jordan Akins has a chance to be productive this year, given that the Texans had nothing else at the position.
Anthony Miller, WR, Bears
There's an outside chance Anthony Miller could become Chicago's No. 2 receiver this season, but I like him better for the long haul. I would not draft him in standard formats this year.
J'Mon Moore, WR, Packers
J'Mon Moore has a chance to be productive right away, as there's a vacancy in Green Bay's receiving corps in the wake of Jordy Nelson's departure.
Tre'Quan Smith, WR, Saints
Third-rounder Tre'Quan Smith could become the No. 2 wideout this year, depending on what happens with Cameron Meredith's health situation. However, given that Drew Brees is 39, Smith won't have elite quarterbacking for long.
Nyheim Hines, RB, Colts
Nyheim Hines will act as a very poor man's Darren Sproles in the Colts' offense. He's worth more in PPR formats.
Dalton Schultz, TE, Cowboys
There's a chance fourth-rounder Dalton Schultz becomes Dallas' starting tight end in the wake of Jason Witten's retirement, so that puts him on the fantasy radar.
Kalen Ballage, RB, Dolphins
Kalen Ballage figures to take over as the starting running back in the event of a Kenyan Drake injury, so he's someone to monitor on the waiver wire.
James Washington, WR, Steelers
James Washington is unquestionably the third receiver, at best, on Pittsburgh's roster, so he'll need Antonio Brown or JuJu Smith-Schuster to get hurt to make any sort of fantasy impact.
Ian Thomas, TE, Panthers
Ian Thomas is an ultra-athletic tight end who should take over Greg Olsen's job once Olsen retires.
Baker Mayfield, QB, Browns
It's unclear if Baker Mayfield will see action until late in 2018, but he's someone to monitor in the future because of his scrambling ability.
Daurice Fountain, WR, Colts
Daurice Fountain is just a fifth-round rookie, but he'll have an opportunity to play right away in Indianapolis. If Andrew Luck returns, Fountain might actually be productive immediately.
Josh Allen, QB, Bills
Josh Allen has accuracy issues, but he's a big-armed, hard-working, mobile quarterback who should be able to post some strong fantasy performances.
Sam Darnold, QB, Jets
Sam Darnold doesn't appear to be a desirable fantasy option in the near future, as the Jets' offense is lacking in weaponry beyond Robby Anderson.
Josh Rosen, QB, Cardinals
Josh Rosen has a chance to play sooner rather than later because of Sam Bradford's injury history, but his lack of passion for football could mean that he'll have a brief career.
Lamar Jackson, QB, Ravens
Lamar Jackson has great fantasy potential because of his legs, but he may not play until 2020 because of Joe Flacco's albatross of a contract.
Dallas Goedert, TE, Eagles
Dallas Goedert was selected in the second round to be Trey Burton's replacement. He'll only be a fantasy factor if Zach Ertz gets hurt.
