NFL Combine 2012 Results: Breaking Down Sunday's Best 40-Yard Dash Performances

It's the premier event at one of the most exciting events in the NFL offseason—the 40-yard dash at the NFL Combine.

And on Sunday, a few players at the quarterback, wide receiver and running back positions seriously impressed scouts and front office personnel with blazing times.

But who were these speed demons? What were their times? And how, exactly, will this affect their draft stock going forward?

Thankfully for you, I've got the answers.

Travis Benjamin, WR, Miami

Best Unofficial Time: 4.32

Official Time: 4.36

How it Impacted His Stock: Benjamin's game is speed and quickness (he's only 5'10"), so his extremely fast time proves what scouts already thought about him. Benjamin stood to lose more with a bad time than he stood to gain with a good one, so not much has changed.

Teams will look at Benjamin as a potential return man at the next level as well, so the fact that he has breakaway speed is a big plus for the small receiver.

Chris Owusu, WR, Stanford

Best Unofficial Time: 4.32

Official Time: 4.36

How it Impacted His Stock: NFL teams will have concerns with the concussions that have limited Owusu since 2009, and he may be looked at primarily as a returner at the next level.

Still, a 4.36 will open eyes, and teams will continue to do their homework on Mr. Owusu. This will only help him.

Chris Rainey, RB, Florida

Best Unofficial Time: 4.37

Official Time: 4.45

How it Impacted His Stock: As expected, Rainey was fast and absolutely exploded out of the blocks. Still, Rainey would have seriously turned heads if he was closer to a 4.30 and likely drawn additional interest from NFL teams.

As Mike Mayock has mentioned throughout the day, Rainey is a smart pick for a team willing to find ways to get him touches as both a runner and receiver, a la Dexter McCluster.

He proved today that he has the burst and speed to potentially be a game-breaker if a team is willing to find creative ways to involve him in the offense.

Russell Wilson, QB, Wisconsin

Best Unofficial Time: 4.50

Official Time: 4.55

How it Impacted His Stock: Wilson is an interesting figure. On one hand, he's a natural leader and an excellent passer who proved with his forty that he has the speed to do damage if he escapes the pocket.

On the other, he's only 5'11", which concerns NFL teams who prefer taller quarterbacks. This forty time will certainly help, but trying to ascertain where Wilson will land is still a mystery.

David Wilson, RB, Virginia Tech

Best Unofficial Time: 4.40

Official Time: 4.49

How it Impacted His Stock: The electrifying Wilson, who was the 2011 ACC Player of the Year, certainly backed up the explosion he shows on the field with a strong 40.

Wilson isn't the most orthodox runner, but he has big-play potential and is excellent coming out of the backfield as a wide receiver. He's a player that will truly intrigue teams with his pure athleticism.

Isaiah Pead, RB, Cincinnati

Best Unofficial Time: 4.41

Official Time: 4.47

How it Impacted His Stock: Pead solidified himself as a second-round talent with his 40 time. Sometimes, doing what is expected of you in the 40 is the best possible outcome.

Chris Givens, WR, Wake Forest

Best Unofficial Time: 4.37

Official Time: 4.41

How it Impacted His Stock: Givens was an All-ACC first-team selection this past year and was a receiver thought to be a second-round value, so his excellent time certainly bolstered an already-strong resume.

Though only 5'11", he was an excellent deep threat for the Wake Forest offense, and his 40 time is an indication that he might be able to replicate that role at the pro level.

Tommy Streeter, WR, Miami

Best Unofficial Time: 4.34

Official Time: 4.40

How it Impacted His Stock: Streeter is 6'5" and 220 pounds, so for him to run a 4.40 is just absurd. He only started one year at Miami and isn't the most polished receiver, though his combination of size and speed will certainly warrant some long looks by NFL teams.

Streeter might sneak into the late second round if teams like what they see upon further inspection.

Andrew Luck, QB, Stanford

Best Unofficial Time: 4.59

Official Time: 4.67

How it Impacted His Stock: It probably didn't, though it should be noted that Cam Newton ran a 4.59 at the Combine last year. In other words, Mr. Luck is an impressive athlete on top of being arguably the best pocket passer to enter the draft since Peyton Manning.

Indianapolis Colts fans, get excited—the next 10 to 15 years of your franchise are in good hands.

LaMichael James, RB, Oregon

Best Unofficial Time: 4.37

Official Time: 4.45

How it Impacted His Stock: The size and durability of James has been questioned by NFL folks, so James' needed to prove he had the burst and agility at the NFL level to make plays.

He certainly proved he had the burst. For my money, James should at least be an excellent scat back in the ilk of a Darren Sproles. I wouldn't be surprised to see a team take James in the second round based on his big-play potential, namely a squad like the Detroit Lions.

Stephen Hill, WR, Georgia Tech

Best Unofficial Time: 4.30

Official Time: 4.36

How it Impacted His Stock: Standing at 6'4" and weighing 215 pounds, Hill seriously opened eyes when he blazed through his 40. His college numbers aren't impressive—he played in a run-first, option offense at Georgia Tech—though he did lead the nation in yards per catch this year (29.3 YPC).

Hill's combination of size and speed may lead to some "Poor man's Randy Moss" comparisons, and Hill's time might be enough that a team would take a chance on selecting him in the second or even late-first round.

Lamar Miller, RB, Miami

Best Unofficial Time: 4.38

Official Time: 4.40

How it Impacted His Stock: Miller proved the burst that shows up on his game tapes with a smoking 40 at the Combine. Don't be surprised if he is the second running back off the board behind Trent Richardson and goes in the second half of the first round.

Michael Floyd, WR, Notre Dame

Best Unofficial Time: 4.42

Official Time: 4.47

How it Impacted His Stock: Floyd may have ensured that he'll be the second wide receiver taken off the board in the draft.

His combination of size, speed and production at the college level is impressive. With South Carolina's Alshon Jeffery surprisingly not running the 40 today, Floyd made the biggest splash of the day thus far for receivers thought to be first-round prospects.

Robert Griffin III, QB, Baylor

Best Unofficial Time: 4.38

Official Time: 4.41 

Position: QB

How it Impacted His Stock: The St. Louis Rams must be giddy right now. With Griffin's blazing time, he's probably all but assured that a team will trade up to the second overall pick and pay a bounty to the Rams to do so.  

His time is also an indication that Griffin will be one of the most compelling athletes at the quarterback position. He's faster than Cam Newton, and bigger than Michael Vick.

Are you excited to watch this guy at the next level yet?

Because I am.
