2012 NFL Mock Draft: How the Combine Has Altered the Draft's First Round

It's day five of the 2012 NFL Scouting Combine, which means that the defensive linemen and linebackers are taking the field for workouts while offensive stars such as quarterbacks Andrew Luck of Stanford and Baylor's Robert Griffin have put the combine in their rearview mirror and are headed home.

The strong showings in Indianapolis turned in by the likes of Boise State running back Doug Martin and disappointing outings like those turned in by Baylor wideout Kendall Wright have sent shockwaves rippling across the draft landscape, and here's a look at how those performances could impact the first round of April's NFL draft.

1. Indianapolis Colts: Andrew Luck, QB, Stanford: Luck showed excellent athleticism and mobility at the combine, and while he chose not to throw, Luck remains a lock to be the draft's top pick.

2. Washington Redskins (from St. Louis Rams): Robert Griffin, QB, Baylor: Griffin wowed scouts in interviews and ran a blistering 4.41 second 40-yard dash, and the Redskins are reportedly poised to make the Rams a "godfather" offer for the second overall selection.

3. Minnesota Vikings: Matt Kalil, OT, USC: The Vikings may miss out on the Robert Griffin sweepstakes, but landing the draft's best left tackle prospect isn't a bad consolation prize.

4. Cleveland Browns: Trent Richardson, RB, Alabama: The Browns apparently aren't as gung-ho as the Redskins to pony up the haul required to land the Griffin pick, which could send a team desperate for playmakers on offense looking towards the draft's top ballcarrier.

5. Tampa Bay Buccaneers: Morris Claiborne, CB, LSU: With Ronde Barber nearing the end of the line and Aqib Talib in constant trouble off the field, the Bucs need to upgrade their secondary.

6. St. Louis Rams (from Washington Redskins): Justin Blackmon, WR, Oklahoma State: This is a best case scenario for the Rams, who would pick up extra picks and still get the player they were targeting all along in the Biletnikoff Award winner.

7. Jacksonville Jaguars: Quinton Coples, DE, North Carolina: With leading pass-rusher Jeremy Mincey set to hit free agency, the Jags need help along the front four, and Coples ran an impressive 1.63 second 10-yard split at the combine Monday.

8. Miami Dolphins: Riley Reiff, OT, Iowa: Reiff's arm length is a concern after the combine, but the Hawkeyes standout is still the draft's top right tackle prospect, and the Dolphins sorely need a replacement for Marc Colombo on that side of the offensive line.

9. Carolina Panthers: Melvin Ingram, DE, South Carolina: If Ingram can put together a good showing in drills, he could easily appeal to the Panthers here given his versatility and penchant for getting after the quarterback.

10. Buffalo Bills: Michael Brockers, DT, LSU: The Bills switch to the 4-3 defense leaves them with a need at defensive end, but the selection of Ingram and Coples before their pick will send Buffalo looking to address the interior of the defensive line.

11. Kansas City Chiefs: Jonathan Martin, OT, Stanford: The Chiefs are need of improvement along the offensive front, and Martin could easily slide over to right tackle and start from day one.

12. Seattle Seahawks: Ryan Tannehill, QB, Texas A&M: Tarvaris Jackson isn't the long-term answer at quarterback, so the Seahawks may turn to Tannehill if he performs well in his pro day.

13. Arizona Cardinals: Courtney Upshaw, OLB, Alabama: The All-American would provide a much needed boost, as the Cardinals got precious little production from their outside linebackers last year.

14. Dallas Cowboys: Janoris Jenkins, CB, North Alabama: Dallas has been known to take chances on talented players with checkered pasts, and this year will be no different.

15. Philadelphia Eagles: Zach Brown, OLB, North Carolina: The Eagles have holes in the linebacker corps, and head coach Andy Reid has been known to go gaga over athletic players like Brown in the past.

16. New York Jets: Whitney Mercilus, DE/OLB, Illinois: The Jets need to improve their front seven, and the NCAA sack leader from 2011 would certainly improve Gang Green's pass rush.

17. Cincinnati Bengals (from Oakland Raiders): David DeCastro, OG, Stanford: Cincinnati has other areas of need, but DeCastro would simply be too good to pass up here after an outstanding combine.

18. San Diego Chargers: Michael Floyd, WR, Notre Dame: With wide receiver Vincent Jackson set to potentially depart in free agency, the Bolts may be left with a hole to fill at the position.

19. Chicago Bears: Kendall Wright, WR, Baylor: Wright had a miserable outing in Indianapolis, but if the speedster can rebound at Baylor's pro day, he'd likely appeal to the wideout-needy Bears here.

20. Tennessee Titans: Andre Branch, DE, Clemson: The Titans are in dire need of improvement on the defensive line, and Branch's stock is on the rise after looking quick at the combine.

21. Cincinnati Bengals: Dre Kirkpatrick, CB, Alabama: If Reggie Nelson departs in free agency, the Bengals have a hole at free safety in addition to the one they already have at cornerback.

22. Cleveland Browns: Alshon Jeffery, WR, South Carolina: Jeffery's stock is tumbling after electing not to run at the combine, but the Browns are desperate for help on offense.

23. Detroit Lions: Cordy Glenn, OG, Georgia: In addition to holes in the secondary, the Lions could also use help up front on offense, and the beefeater from Georgia would plug one of those holes.

24. Pittsburgh Steelers: Dontari Poe, DT, Memphis: The 346-pound behemoth racked up 44 reps in the bench press at the combine and would fill an area of need for the Steelers at nose tackle.

25. Denver Broncos: Fletcher Cox, DT, Mississippi State: The Broncos will make it two tackles in a row by selecting the Bulldogs standout, as the interior of the defensive line was a weakness for the Denver defense a season ago.

26. Houston Texans: Dont'a Hightower, ILB, Alabama: DeMeco Ryans struggled on the inside of the Texans 3-4 defense last year, so Houston could look to get better at that slot.

27. New England Patriots: Nick Perry, DE/OLB, USC: The Patriots need to get younger on defense, and Perry would offer the sort of versatility that will appeal to Bill Belichick.

28. Green Bay Packers: Devon Still, DT, Penn State: The Packers defense was a statistical mess last year due in large part to their inability to pressure the quarterback consistently.

29. Baltimore Ravens: Peter Konz, C, Wisconsin: With starter Matt Birk contemplating retirement, the Ravens need to procure a potential replacement early in the draft.

30. San Francisco 49ers: Stephen Hill, WR, Georgia Tech: Hill was the star of the combine at his position and the 49ers badly need to bolster their receiving corps.

31. New England Patriots: Alfonzo Dennard, CB, Nebraska: The Patriots are desperate for help in the defensive backfield even if this pick seems like something of a reach.

32. New York Giants: Coby Fleener, TE, Stanford: A strong combine could vault Fleener into the draft's first round, where he could appeal to a team with a need at the position like the defending Super Bowl champs.
