Top NFL Draft college prospects at every position image

With the Super Bowl complete and another NFL season officially in the books, all 32 teams can now fully entrench themselves in the draft process.

The NFL combine beginning Feb. 17 is the next step. Players like USC's Leonard Williams and Nebraska's Randy Gregory lead their respective groups for now, but the top spot for each position in the 2015 class is still very much up for grabs.

Here are our current rankings for each position. 

Quarterbacks 

1. Marcus Mariota, Oregon

2. Jameis Winston, Florida State

3. Brett Hundley, UCLA

4. Garrett Grayson, Colorado State

5a. Chris Bonner, Colorado State-Pueblo

5b. Brandon Bridge, South Alabama

The battle/debate between Mariota and Winston will persist right up until the draft. But after those two, both of which have questions as to whether they're "franchise quarterback" options, the crop drops off in talent. Flashes from Hundley could push him into the top 40, but the rest have value starting in Round 4. Both Bonner and Bridge have loads of upside but are works in progress.

Running backs

1. Todd Gurley, Georgia

2. Melvin Gordon, Wisconsin

3. Jay Ajayi, Boise State

4. Duke Johnson, Miami (Fla.)

5a. David Johnson, Northern Iowa

5b. Tevin Coleman, Indiana

5c. David Cobb, Minnesota

If not for injury, Gurley would be in the Adrian Peterson discussion in terms of best running back prospects of the last decade. He and Gordon are firm first-round options despite the position being devalued in recent years. Between Ajayi and Cobb, there’s not much separation in talent level, which should mean a strong run on running backs between picks 45 and 70.

Wide receivers

1. Jaelen Strong, Arizona State

2. Amari Cooper, Alabama

3. DeVante Parker, Louisville

4. Kevin White, West Virginia

5. Justin Hardy, East Carolina

After receivers highlighted the 2014 draft class, this year's group also features awesome depth with no clear-cut No. 1. Cooper and White have received the most attention due to their NFL-readiness, but Strong and Parker also have feature receiver potential.

Tight ends

1. Devin Funchess, Michigan

2. Maxx Williams, Minnesota

3. Tyler Kroft, Rutgers

4. Jeff Heuerman, Ohio State

5. Clive Walford, Miami (Fla.)

If Funchess is considered a tight end, he's a clear No. 1. A proficient blocker in the open field, Funchess' versatility as a receiver, slot option and seam threat puts him in top 20 overall consideration. Williams is complete as a plus-blocker and a threatening short- to mid-range target. Kroft and Walford have upside as pass catchers.

Offensive tackles

1. La’el Collins, LSU

2. Jake Fisher, Oregon

3. Andrus Peat, Stanford

4. Ereck Flowers, Miami (Fla.)

5a. Brandon Scherff, Iowa

5b. TJ Clemmings, Pittsburgh

Despite Senior Bowl struggles, Collins remains our top tackle. He’s a devastating run blocker who does just enough with hand strength and a good base to be a proficient pass blocker. Both Fisher and Peat flash franchise left tackle potential, especially as pass blockers. Flowers and Scherff are viewed as safe options, either at tackle or guard.

Guards

1. Laken Tomlinson, Duke

2. A.J. Cann, South Carolina

3. Tre Jackson, Florida State

4. Josue Matais, Florida State

5. Arie Kouandjio, Alabama

We likely won't see any guards go in the first round this year, but both Tomlinson and Cann are viewed as great second-round options. Both FSU guards, especially Jackson and his massive frame, appear NFL-ready.

Centers

1. Cameron Erving, Florida State

2. Hroniss Grasu, Oregon

3. Reese Dismukes, Auburn

4. Andy Galik, Boston College

5. Collin Rahrig, Indiana

After switching from tackle to center in the middle of the season, Erving went from disappointing starter to the best center in the class and in the first-round mix. Grasu has a tremendous resume, but he may only fit zone blocking teams. Dismukes, Galik and Rahrig show starter upside but likely will be picked outside the top 100.

Defensive tackles

1. Leonard Williams, USC

2. Eddie Goldman, Florida State

3. Jordan Phillips, Oklahoma

4. Malcom Brown, Texas

5. Danny Shelton, Washington

The best player in the class at this point, Williams features everything scouts love in a defensive line prospect: athleticism, versatility and plenty of room to grow. Goldman was a bit unheralded during the season, but he's worth a top 10 pick. Phillips and Brown are in the late first-round mix as impact interior run defenders. Shelton, despite high praise as an interior-controlling presence, is limited as a pass rusher and only fits teams looking for two-down players.

Defensive ends

1. Randy Gregory, Nebraska

2. Alvin Dupree, Kentucky

3. Shane Ray, Missouri

4. Owamagbe Odighizuwa, UCLA

5a. Arik Armstead, Oregon

5b. Eli Harold, Virginia

5c. Mario Edwards, Florida State

In maybe the best position group of the class, Gregory and Dupree offer the highest ceiling of any players. Gregory's athleticism in space and Dupree's explosiveness off the edge merit both being a top 10 pick. Ray is viewed highly by some teams, but he's more of a high-energy player. Odighizuwa and Armstead flash use of their length and violent bull rush but are not yet finished products.

Outside linebackers

1. Shaq Thompson, Washington

2. Dante Fowler, Florida

3. Paul Dawson, TCU

4. Martrell Speight, Arkansas

5. Lorenzo Mauldin, Louisville

Though his true NFL position isn't clear, Thompson's fluidity, athleticism and explosiveness is too impressive to pass on. Fowler is NFL-ready thanks to hand quickness and decisiveness, but his upside doesn't offer what other edge players in this class can — he may be suited for a 4-3 scheme. Dawson has character woes, but talent-wise, he's worthy of a top 40 pick.

Inside linebackers

1. Eric Kendricks, UCLA

2. Denzel Perryman, Miami (Fla.)

3. Benardrick McKinney, Mississippi State

4. Hayes Pullard, USC

5. Stephone Anthony, Clemson

The two best inside linebackers in this class offer much of the same: quickness, instincts to back it up and decisive reads to finish plays in traffic. Kendricks has a better NFL body than Perryman. McKinney has received attention, but concerns about whether he's able to play all three downs in the pros pushes him to third for us. Pullard and Anthony used great Senior Bowl performances to get them into top 100 consideration.

Cornerbacks

1. Trae Waynes, Michigan State

2. P.J. Williams, Florida State

3. Jalen Collins, LSU

4. Quentin Rollins, Miami (Ohio)

5. Marcus Peters, Washington

No corner merits a top 10 pick at this point, but the class features strong options for teams in the middle of the first round and through the second. Waynes has the best upside, and he may be the consensus top corner after the Combine. Williams offers physicality and Collins has length. Rollins and Peters have the fluidity and developmental upside to merit first-round consideration.

Safeties

1. Landon Collins, Alabama

2. Eric Rowe, Utah

3. Jaquiski Tartt, Samford

4. Chris Hackett, TCU

5. Cody Prewitt, Ole Miss

Collins appears to be the clear-cut top safety prospect and could fit most NFL defenses, but recent Alabama defensive back struggles may hurt his stock. Rowe is a cornerback/safety in-betweener, but he offers control and instincts greater than most in the class. Tartt (strong safety) has the athletic upside to develop into a top pro player, but he'll need time to transition. He still could land within the first two rounds if he tests as well as expected.
