Mel Kiper's top 10 prospects at each position for 2018 NFL draft

— -- Time for my latest position rankings for the 2018 NFL draft, which combines seniors and underclassmen and features a top 10 for every position.?

Quarterbacks

1. * Josh Rosen, UCLA

2. ** Sam Darnold, USC

3. * Josh Allen, Wyoming

4. Baker Mayfield, Oklahoma

5. * Drew Lock, Missouri

6. Mason Rudolph, Oklahoma State

7. * Lamar Jackson, Louisville

8. Mike White, Western Kentucky

9. Luke Falk, Washington State

10. Kurt Benkert, Virginia

Lock is an underclassman to keep an eye on. He really finished the season strong as Missouri won six straight games and he had 43 touchdown passes to 12 interceptions.

Running backs

1. * Saquon Barkley, Penn State

2. * Bryce Love, Stanford

3. * Derrius Guice, LSU

4. * Ronald Jones II, USC

5. * Damien Harris, Alabama

6. Nick Chubb, Georgia

7. * Kerryon Johnson, Auburn

8. Rashaad Penny, San Diego State

9. Royce Freeman, Oregon

10. Sony Michel, Georgia

So Barkley is the clear No. 1, and after that it's going to come down to testing numbers at the combine. Harris is one of my favorite prospects in this class. Johnson is banged up but has had a breakout 2017 season.

Fullbacks/H-backs

1. Jaylen Samuels, NC State

2. Dimitri Flowers, Oklahoma

3. Nick Bawden, San Diego State

4. Khalid Hill, Michigan

5. * Winston Dimel, Kansas State

6. Austin Ramesh, Wisconsin

7. Daniel Marx, Stanford

8. Garrett Dickerson, Northwestern

9. J.D. Moore, LSU

10. * Alec Ingold, Wisconsin

Bawden is the best bruising fullback -- he's 6-foot-3, 245 pounds, and paves the way for fringe Heisman candidate Rashaad Penny.

Wide receivers

1. * Calvin Ridley, Alabama

2. * Courtland Sutton, SMU

3. Anthony Miller, Memphis

4. * Christian Kirk, Texas A&M

5. Michael Gallup, Colorado State

6. * D.J. Moore, Maryland

7. * Jordan Lasley, UCLA

8. *Simmie Cobbs, Indiana

9. * Parris Campbell, Ohio State

10. James Washington, Oklahoma State

Lasley has come on as Josh Rosen's No. 1 target, finishing the regular season with back-to-back 200-yard games.

Tight ends

1. Dallas Goedert, South Dakota State

2. * Mark Andrews, Oklahoma

3. Mike Gesicki, Penn State

4. Ian Thomas, Indiana

5. * Hayden Hurst, South Carolina

6. Durham Smythe, Notre Dame

7. Troy Fumagalli, Wisconsin

8. Tyler Conklin, Central Michigan

9. * C.J. Conrad, Kentucky

10. Christopher Herndon, Miami (Fla.)

Smythe has only 26 career catches for the Fighting Irish, but he has some receiving skills. He might be a better pro than college player.

Offensive tackles

1. Mike McGlinchey, Notre Dame

2. * Connor Williams, Texas

3. * Orlando Brown, Oklahoma

4. Martinas Rankin, Mississippi State

5. Chukwuma Okorafor, Western Michigan

7. Tyrell Crosby, Oregon

8. Timon Parris, Stony Brook

9. Brandon Parker, NC A&T

10. Jamarco Jones, Ohio State

Harrison is a Texas transfer who also spent time at a junior college. Jones has really improved from last season.

Offensive guards

1. * Quenton Nelson, Notre Dame

2. Braden Smith, Auburn

3. Will Hernandez, UTEP

4. Isaiah Wynn, Georgia

5. Cody O'Connell, Washington State

6. * Sam Jones, Arizona State

7. Brendan Mahon, Penn State

8. Austin Corbett, Nevada

9. KC McDermott, Miami (Fla.)

10. Wyatt Teller, Virginia Tech

O'Connell is massive -- 6-foot-8, 354 pounds.

3. * Rasheem Green, USC

4. * Sam Hubbard, Ohio State

4. * Justin Reid, Stanford

5. Armani Watts, Texas A&M
