Pac-12 Perspective 2015 NFL Mock Draft 10/24: Leonard Williams and Marcus Mariota go one-two

Throughout the season and more frequently leading up to the NFL Draft when then the season is over, will update my Pac-12 Perspective NFL Mock Draft that exclusively focuses on the Pac-12 players that I think will go in the first round of the draft. I put the order together by how I think the NFL standings will finish.

1. Oakland - Leonard Williams DT USC *Jr.

Despite likely finishing the season with the NFL's worst record, it appears right now that the Raiders are willing to stick with Derek Carr at quarterback for a while. If there was an Andrew Luck type available, I think they might take him and figure out what to do with Carr, but I am not a fan of this year's likely quarterback class and don't think they will reach for any of them. They could easily trade down to one of the many teams in the draft who really need a quarterback, but I don't predict trades in my mocks, just too difficult.

With that out of the way, I think the Raiders can simply take the best player available and that is the big, athletic and versatile Williams who could be the cornerstone of a defense.

2. Tampa Bay - Marcus Mariota QB Oregon *Jr.

The Buccaneers have a wealth of problems, but none more glaring than quarterback and they have will have a great chance to address it at the top of the draft in 2015. I think Winston is the best quarterback prospect in the draft, but his colossal baggage pushes Mariota ahead of him. He will need to do a lot of work on pocket passing at the next level, but Mariota's poise and feel for the game set him apart from the rest of the non-sketchy quarterbacks in this class. On top of that, his squeaky clean image is perfect to put as the face of a franchise.

3. Tennessee - Jameis Winston QB Florida State *So.

4. Jacksonville - Cedric Ogbuehi T Texas A&M

5. Washington - Randy Gregory DE Nebraska *Jr.

6. Minnesota - Landon Collins S Alabama *Jr.

7. Jets - Amari Cooper WR Alabama *Jr.

8. Atlanta - Shawn Oakman DE Baylor *Jr.

9. Cleveland - Andrus Peat T Stanford *Jr.

The Browns are riding high and have a very favorable schedule for the first half of the season, but I think they will slowly plummet once their schedule starts toughening up. They are going to need to start building up around Johnny Manziel if they hope to turn the corner with him and getting another standout offensive linemen to join Joe Thomas would help with that.

Peat might have the most potential of any offensive lineman in the draft with his size and athleticism and comes with the Stanford offensive lineman pedigree, making him an excellent candidate to help the Browns at right tackle.

10. St. Louis - Connor Cook QB Michigan State *Jr.

11. Cleveland (from Buffalo) - Kevin White WR West Virginia

12. Kansas City - Marcus Peters CB Washington *Jr.

The Chiefs are improving, but will still fall well short of the playoffs and really need help at cornerback. Peters is rising right now and turning into the draft's top cornerback prospect due to his ideal size and aggressiveness as he already has three interceptions this season. His intensity can sometimes get the best of him and got him a one-game internal suspension, but is also what makes him such a competitor so I think NFL teams will be fine with it.

13. Carolina - Brandon Scherff T Iowa

14. Houston - Brett Hundley QB UCLA *Jr.

I don't think the Texans are very good, but they will finish with a decent record because they play in a bad division. I could see them trading up to get a quarterback, but that won't be easy with three teams in the Top 10 needing QBs and not many good ones to go around this year. I think they can still get the last first round worthy QB at this point in the draft in Hundley, who looks to continue to have consistency and decision making issues, but has the physical tools that are too good to pass up when you need a QB as bad as Houston does.

15. Miami - Vic Beasley DE Clemson

16. Pittsburgh - Trae Waynes CB Michigan State *Jr.

17. Detroit - P.J. Williams CB Florida State *Jr.

18. Chicago - Dante Fowler Jr. DE Florida *Jr.

19. San Francisco - Devin Funchess WR Michigan *Jr.

20. Seattle - Jaelen Strong WR Arizona State *Jr.

The Seahawks are finding out just how hard it is to repeat a Super Bowl championship, especially when you have injury problems and play in a tough division. I think they get very close to the playoffs, but just miss out in a very tough NFC. The Seahawks need a star at receiver that can help out Russell Wilson after losing Golden Tate and Percy Harvin and Strong could fit the bill. He has a rare combination of having the size and range of a possession receiver with the speed of a deep threat.

21. New Orleans - Ifo Ekpre-Olomu CB Oregon

The Saints are looking bad right now but I think they end up winning the NFC South with a like an 8-8 record. They could use help a lot of places, but cornerback is a glaring need and there will still be a lot of good ones left at this stage in the first round. Team have gone at Ekpre-Olomu with success this season and I think it has pushed him down the chart of cornerbacks in this class, but his overall book of work probably still keeps him in the first round.

22. New England - Danny Shelton DT Washington

The Patriots will struggle this season but still end up winning a soft AFC East. They need help all across the board but maybe nowhere more than up front on their defense where Vince Wilfork is getting up there in age. I am wary of putting Shelton in the first round since giant defensive tackles like him are starting to drop in draft value in general, but I think he has shown enough versatility this season to show that he can be a dynamic player at the next level and not just a middle run plugger.

23. San Diego - La'el Collins T LSU

24. Giants - Shilique Calhoun DE Michigan State *Jr.

25. Baltimore - Todd Gurley RB Georgia *Jr.

26. Cincinnati - Shane Ray DE Missouri *Jr.

27. Green Bay - Eddie Goldman DT Florida State *Jr.

28. Dallas - Arik Armstead DT Oregon *Jr.

The Cowboys are surprisingly maybe the NFL's hottest team and while I don't think they are going to win the Super Bowl, I think they will have a decent playoff run for once. The main reason I don't see them going all the way is because their defense needs a lot of help everywhere. Armstead is a bit like the Pac-12's Shawn Oakman in that he looks like a bulked up NBA power forward that is a monster all across the defensive line. Injuries have limited his overall impact thus far this season, but he should be a force for the Ducks up front if he can stay healthy and his measurable alone probably make him a first round pick.

29. Indianapolis - Markus Golden DE Missouri

30. Philadelphia - Ronald Darby CB Florida State *Jr.

31. Arizona - Shaq Thompson LB Washington *Jr.

The Cardinals look like the best team in the NFC thus far and I think they will hold onto that title. They could use some more pass rushers and there are a ton of good ones available in this draft. I am not as big on Thompson as an NFL prospect as others because I think he is a bit of a tweener, but his raw abilities are going to be too good to not get him taken in the first round as a pure defensive playmaker.

32. Denver - Bernardrick McKinley LB Mississippi State
