2012 NFL Mock Draft: Updated Full First-Round Mock After Combine

And the stock roller coaster ride has begun.

While a number of prospects boosted their stock this past weekend, a handful shot themselves in the foot. Poor weigh-ins and workouts resulted in that handful of athletes' names doing a disappearing act; you won’t find them in this updated preview.

Halfway through the 2012 NFL Combine, here is a full first-round mock draft:

1. Indianapolis Colts: Andrew Luck (QB, Stanford)

Luck would’ve had to balloon like JaMarcus Russell to fall from No. 1 overall. Running a 4.67 40-yard dash wasn’t enough to do him in.

2. Cleveland Browns: Robert Griffin III (QB, Baylor)

After RGIII’s combine performance, Cleveland packaging their pair of first-round selections to trade up for him is a lock. Griffin ran a jaw-dropping 4.41 40-yard dash, the third-fastest time ever for a quarterback.

3. Minnesota Vikings: Matt Kalil (OT, USC)

As much as Christian Ponder would love to possess an arsenal that didn’t include Michael Jenkins and Devin Aromashodu as key weapons, I’m sure at the same time he wouldn’t mind a protection upgrade. Kalil weighed in at 6’6”, 306 pounds and benched 225 pounds 30 times.

4. St. Louis Rams: Justin Blackmon (WR, Oklahoma St.)

After trading down, St. Louis misses out on adding a franchise left tackle, but Sam Bradford finally finding a No. 1 receiver isn’t a bad consolation prize. Blackmon didn’t run at the combine because of a hamstring injury, but after hauling in 121 receptions for 1,522 yards and 18 touchdowns this season, he doesn’t need to prove much to scouts.

5. Tampa Bay Buccaneers: Morris Claiborne (CB, LSU)

Aqib Talib will potentially go from being a lockdown corner to being locked up in prison while Ronde Barber is nearly fossilized. Claiborne is the most talented defender in the draft and fills a major need for the Bucs.

6. Washington Redskins: Riley Reiff (OT, LSU)

Whoever their quarterback is next season—Peyton Manning, Matt Flynn or Mike Shanahan’s favorite quarterback of all-time John Beck—he’ll need an upgraded offensive line to stay upright. Reiff didn’t impress at the combine, but he didn’t hurt himself enough for the Skins, who lack options, to go elsewhere.

7. Jacksonville Jaguars: Jonathan Martin (OT, Stanford)

Blaine Gabbert needs an upgraded offensive line and receiving corps and Martin is the best player that fills either need. Food poisoning prevented him from benching, but he looked fluid in workouts and he measured in at 6’5”, 312 pounds.

8. Miami Dolphins: Quinton Coples (OLB, North Carolina)

Miami needs to find a pass-rusher opposite Cameron Wake. Coples who weighed in at 6’6”, 284 pounds would do the trick.

9. Carolina Panthers: Michael Brockers (DT, LSU)

After entering the combine with the reputation of an explosive lineman and measuring in at a whopping 6’5”, 322 pounds, Brockers is close to being a top-10 lock. Carolina’s defense needs to at least come close to matching their offense’s performance and their largest hole is on their interior line.

10. Buffalo Bills: Melvin Ingram (DE, South Carolina)

Buffalo’s pass rush ranked 27th in the league last season in sacks. The 6’1”, 264-pound Ingram continues to lose weight, but he’s the only 4-3 defensive end prospect left worthy of being selected at this point in the draft.

11. Kansas City Chiefs: Trent Richardson (RB, Alabama)

If Richardson falls this far, Kansas City has a no-brainer on their hands. With Jamaal Charles coming off a torn ACL and Thomas Jones being a shell of his former self, the Chiefs need a halfback.

12. Seattle Seahawks: Ryan Tannehill (QB, Texas A&M)

The Plain Dealer’s Mary Kay Cabot relayed this Mike Mayock message via Twitter which will have a huge effect on the first day of the draft:

"

NFL network's mike Mayock said he wouldn't be surprised if qb Ryan tannehlll goes in the top 10.

— Mary Kay Cabot (@MaryKayCabot) February 26, 2012"

Pete Carroll can’t go into the 2012 campaign with Tarvaris Jackson as his starting QB and seriously believe that his team is capable of contending for a title.

13. Arizona Cardinals: David DeCastro (G, Stanford)

Arizona must protect that quarterback in Kevin Kolb that they just spent so much to get. With no worthy offensive tackle on the board, DeCastro is an excellent plan B.

14. Dallas Cowboys: Dre Kirkpatrick (CB, Alabama)

Dallas’ secondary is a joke. With holes at cornerback and safety, luckily for the Cowboys, Kirkpatrick is versatile enough to play both.

15. Philadelphia Eagles: Luke Kuechly (ILB, Boston College)

Besides heart, the biggest thing that the Eagles defense is missing is the ability to tackle. The intelligent Luke Kuechly racked up 191 this past season for the Golden Eagles.

16. New York Jets: Courtney Upshaw (OLB, Alabama)

Rex Ryan’s defensive scheme is a nightmare for opposing quarterbacks. Well, at least when the Jets actually field a couple of talented pass-rushers—which they don’t currently have—it is.

17. Cincinnati Bengals: Janoris Jenkins (CB, North Alabama)

As poor as Antonio Cromartie Jr. looks right now, he won’t fall past the Bengals. Jenkins is a top-10 talent and while character concerns should drop him out of the first round, Marvin Lewis will be more than willing to give him another chance.

18. San Diego Chargers: Whitney Mercilus (OLB, Illinois)

San Diego needs a pass-rusher across from Shaun Phillips if the switch back to a 4-3 defense or not. Mercilus is physically gifted enough to play end in a 4-3 or outside linebacker in a 3-4.

19. Chicago Bears: Michael Floyd (WR, Notre Dame)

After running a 4.47 40-yard dash at 6’3”, 220 pounds, Chicago is lucky to get Floyd at this point in the draft. If the Bears are able to gift Jay Cutler with a No. 1 wideout this offseason and re-sign Matt Forte, the Bears will be dangerous.

20. Tennessee Titans: Cordy Glenn (G, Georgia)

Cordy Glenn arguably boosted his stock more than anyone early in the combine. With a gaping hole in their interior offensive line, Tennessee won’t be able to pass up the 6’5”, 345-pound monster that ran a 5.15 40-yard dash.

21. Cincinnati Bengals: Lamar Miller (RB, Miami)

After running a blistering 4.38 40-yard dash at the combine, Miller has solidified himself as a first-round lock. With no talent to be found at the position (yeah, I’m looking at you Cedric Benson), Cincinnati won’t pass on the next great Cane.

22. St. Louis Rams: Devon Still (DT, Penn State)

St. Louis’ defense went from being the strength of the team to part of the problem. Still, who measured in at 6’5”, 303 pounds, would fill a major whole at defensive tackle for the Rams.

23. Detroit Lions: Mark Barron (SS, Alabama)

Detroit’s secondary is the only thing holding its defense back from being dominant. Barron is the most talented defensive back in an extremely thin class and his hard-hitting ability will be welcome in an already fierce unit headlined by Ndamukong Suh.

24. Pittsburgh Steelers: Vontaze Burfict (ILB, Arizona St.)

This pick will come down to Burfict and Dont'a Hightower. With the former Sun Devil's out-of-this-world potential, I can’t imagine the Steelers going the conservative route with their prestigious history of breeding linebackers.

25. Denver Broncos: Fletcher Cox (DT, Mississippi St.)

For a team that advanced to the divisional round of the playoffs, Denver has plenty of holes to fill this offseason. Defensive tackle is their biggest and the 6’4”, 298-pound Cox is capable of filling it.

26. Pittsburgh Steelers: Kendall Wright (WR, Baylor)

Yes, this is currently the Houston Texans selection and no, it won’t be on draft day. With a major need at wide receiver and plenty of cap room, expect the Texans to break the bank for Mike Wallace with an offer that the Steelers will be unable to match.

27. New England Patriots: Nick Perry (OLB, USC)

New England’s defense needs an upgrade on every level, but a rush linebacker is their greatest need. Perry is a physical freak that is versatile enough to play multiple positions in the Pats’ scheme.

28. Green Bay Packers: Peter Konz (C, Wisconsin)

Konz had a horrible combine, only pumping out 18 reps on the bench press. Still, his play on the field will keep him in the first round and the Packers must find a replacement for Scott Wells if they can’t re-sign him.

29. Baltimore Ravens: Dont'a Hightower (ILB, Alabama)

Baltimore must eventually replace Ray Lewis, but even right now, they need an upgrade next to him.  Hightower is a sub-par athlete, but his instincts and skill set are top-notch.

30. San Francisco 49ers: Alshon Jeffery (WR, South Carolina)

As overweight as Jeffery looked during the season, he weighed in at the combine at 6’3”, 216 pounds. He didn’t run, but he’s too talented to pass on for the 49ers whose No. 1 need by far is the receiver position.

31. New England Patriots: Jerel Worthy (DT, Michigan St.)

New England looks to upgrade yet another hole on the Swiss cheese that is their defensive unit. Albert Haynesworth didn’t work out, so Bill Belichick might as well try again with a young, more motivated Worthy.

32. New York Giants: Coby Fleener (TE, Stanford)

Jake Ballard and Travis Beckham both tore ACLs to finish out this season. New York must select the best tight end available to end the first round and right now, the 6’6”, 247-pound Fleener holds that title.
