It's impossible to look at the Cowboys and their No. 4 overall pick and not see it as the fulcrum for this draft. If Dallas decides to take a top defensive player, it's going to squeeze the talent at the top of the draft. If they get bold and go with a stud running back, all eyes are on Jerry Jones.

And what if they actually take a quarterback? There was chatter about it during the Senior Bowl, with Jason Garrett coaching up Carson Wentz. Maybe it's less likely for Dallas to snag a quarterback here given all the issues the Cowboys have for 2016 alone, but it's not unreasonable for the Joneses to consider it.

You only get so many looks at a top-five pick when you're actually in possession of a quarterback who is capable of winning a title (yes Tony Romo is that guy). When Romo is done playing -- and it can't be that long -- having a quarterback groomed behind him would be huge.

There's potential for it to backfire if Romo plays well for four years (see: Denver this year) and all of a sudden you've got a 27-year-old first-round pick and you're not sure whether or not he's capable of leading your team. But if the Cowboys think Romo might not be able to perform at a high level (because of injuries and age) for the next few years, they need to make a move.In the latest rendition of the mock, we've got them doing just that below.

1. Tennessee Titans 

Laremy Tunsil, T, Mississippi: I keep wanting to do something different for Tennessee here (cornerback, pass rusher) but they need to protect Marcus Mariota, just invested in the running game and Tunsil's probably the best player in the draft.

2. Cleveland Browns  

Jared Goff, QB, California: The Colin Kaepernick rumors are starting to cool in Cleveland, which means you can bank on them going quarterback at No. 2. Goff is part of an experiment here, but also very much in play for Cleveland if he's the guy Hue Jackson decides he likes.

3. San Diego Chargers 

DeForest Buckner, DE, Oregon: The Chargers need defensive help and while there might be other candidates here, this is the best combination of scheme and fit.

4. Dallas Cowboys 

Carson Wentz, QB, North Dakota State: Would Dallas be willing to sacrifice a potential impact player for 2016 in order to secure the future? Tony Romo isn't going to play forever.

5. Jacksonville Jaguars  

Jaylen Ramsey, DB, Florida State: The additions for Gus Bradley's defense continue, with the versatile Ramsey able to play all over the place.

6. Baltimore Ravens  

Myles Jack, LB, UCLA:This might not be EXACTLY how things play out in the draft, but Ozzie Newsome walking away with incredible, franchise-altering value from a top-10 pick is what will happen.

7. San Francisco 49ers  

Joey Bosa, DE, Ohio State: With the two quarterbacks off the board and Kaepernick still in house the 49ers will happily snatch up a high-end defensive prospect.

8. Philadelphia Eagles

Ezekiel Elliott, RB, Ohio State: Looking at the teams on the board here it's hard to imagine Zeke getting out of the top 10. He's a worthy candidate with his skills, especially for a team with only Ryan Mathews to lean on.

9. Tampa Bay Buccaneers 

Vernon Hargreaves, CB, Florida: The defense is changing with Lovie Smith gone and it needs some help in the secondary. Picking up a rangy athlete like Hargreaves is a good start.

10. New York Giants  

Ronnie Stanley, OL, Notre Dame: This feels like the ultimate Tom Coughlin pick, which is fun because it would only serve to anger an already angry Coughlin who just had to watch his old team spend big in free agency on defense.

11. Chicago Bears  

William Jackson III, CB, Houston: Just keep coming back to the idea of the Bears snagging a cornerback in the draft. Not like the offense is loaded, but with Kevin White hopefully getting to play this year that side of the ball already has a bonus addition.

12. New Orleans Saints  

Shaq Lawson, DE, Clemson: Defense, defense, defense. It's what the Saints probably need to draft for the next decade. They had success with Lawson's teammate Stephone Anthony last year as well.

13. Miami Dolphins

Kevin Dodd, DE, Clemson: Clemson run! The Dolphins invested in the defensive line this offseason already but Cameron Wake (34) and Mario Williams (31) aren't exactly spring chickens.

14. Oakland Raiders  

Eli Apple, CB, Ohio State: Reggie McKenzie hit gold with David Amerson on waivers but hasn't gotten the production he wants from D.J. Hayden. Dipping into the market for another corner isn't a bad idea at all for a suspect secondary.

15. Los Angeles Rams  

Paxton Lynch, QB, Memphis: Have had this locked in for a while and don't see the need to change it. The Rams are currently planning to start Case Keenum for the entire season and that feels a little bit foolish.

16. Detroit Lions  

Laquon Treadwell, WR, Mississippi: Adding Marvin Jones to Golden Tate is a nice move but they need a big, physical red-zone threat with Calvin Johnson retired. Treadwell is a great answer for that.

17. Atlanta Falcons  

Reggie Ragland, LB, Alabama: Capable, versatile leader for the middle of Dan Quinn's revamped defense.

18. Indianapolis Colts  

Jack Conklin, OT, Michigan State: Ryan Grigson's got to find ways to protect Andrew Luck and get more physical on the offensive line. This helps immediately.

19. Buffalo Bills 

Leonard Floyd, OLB, Georgia: The Bills have talent to be a top-tier defense, even if it didn't flash last year. Rex Ryan getting another pass-rushing piece after Mario Williams left would be a big help.

20. New York Jets  

A'Shawn Robinson, DT, Alabama: Expecting Muhammad Wilkerson might not be a permanent fixture within the Jets organization, the front office adds another big body on the defensive line.

21. Washington Redskins  

Noah Spence, DL, Eastern Kentucky: Scot McCloughan wants talented, physical players and he's willing to gamble Spence's troubles are behind him.

22. Houston Texans  

Will Fuller, WR, Notre Dame: By adding Lamar Miller and Brock Osweiler, the Texans nearly reinvented their offense overnight. Now adding a deep-speed threat across from DeAndre Hopkins puts them over the top.

23. Minnesota Vikings  

Corey Coleman, WR, Baylor: Steal here for the Vikings, desperately in need of help for Teddy Bridgewater. Not a perfect route tree but an explosive playmaker.

24. Cincinnati Bengals 

Josh Doctson, WR, TCU: Receiver run! The Bengals lost both Mohamed Sanu and Marvin Jones during free agency and need help at the position. Give Andy Dalton a weapon from his alma mater.

25. Pittsburgh Steelers  

Mackensie Alexander, CB, Clemson: This is a defense badly in need of help in the secondary. Alexander's (relative) fall here gives them some nice value.

26. Seattle Seahawks 

Derrick Henry, RB, Alabama: Pete Carroll from the top rope! Pete Carroll from the top rope!!! The Seahawks blow the draft wide open by taking a powerful running back to replace Marshawn Lynch. Thomas Rawls fantasy owners cringe, but what a one-two punch the Seahawks have the next three years minimum.

27. Green Bay Packers 

Cody Whitehair, OL, Kansas State: The Packers get more physical and deep on offensive line, with concerns about contracts for Josh Sitton and T.J. Lang coming up.

28. Kansas City Chiefs 

Darron Lee, LB, Ohio State: This speedy linebacker slots in with an already stout defense to give the Chiefs another weapon on that side of the ball.

29. Arizona Cardinals 

Taylor Decker, OL, Ohio State: The Cardinals snag another offensive line prospect to help protect Carson Palmer, giving them a full season to develop Decker if need be.

30. Carolina Panthers  

Emmanuel Ogbah, DE, Oklahoma State: The Panthers defense is stout but it could still use some pass rush help off the edge and Ogbah gives them just that.

31. Denver Broncos  

Jarran Reed, DT, Alabama: Best player available here for the Broncos as they look to fill some of the holes created by the mass exodus during free agency.

Will Jerry Jones shake up the draft and take Carson Wentz at No. 4?(USATSI)
