NFL Free Agency: Top 10 Rookies Who Will Go Undrafted in the 2011 Draft

There is nothing worse for a player than thinking (or hoping) that you'll get drafted in the sixth or seventh round of the NFL draft, but not getting a call on draft day.

Then again, a lot of players go undrafted but turn into legitimate NFL weapons.

The Dallas Cowboys didn't draft Tony Romo, but the quarterback has become a three-time Pro Bowler.

Antonio Gates wasn't drafted, but the San Diego Chargers sure are happy to have the seven-time Pro Bowler on their team.

Same with Danny Woodhead and BenJarvus Green-Ellis, the two running backs for the New England Patriots.

So maybe one of the following 10 players will turn into the next Tony Romo. Or Antonio Gates. Or Woodhead or Green-Ellis. 

Courtney Smith, Wide Receiver, Southern Alabama

Courtney Smith is 6'4 and weighs 223 pounds, but he ran just a 4.65 in the 40-yard dash.

He needs to work on his blocking and he dropped a couple of passes at the Senior Bowl that hurt his overall value.

But Smith is a physical receiver and has ridiculously long arms, which will obviously help him against the taller cornerbacks in the league.

Darren Evans, Running Back, Virginia Tech

Darren Evans is a big runner (6', 227 pounds) who has had injury problems in the past. He missed the entire 2009 season with a torn ACL. 

But he led Virginia Tech to the ACC title, rushing for 12 touchdowns. 

Evans' draft value could be higher if he chose to stay at college for his senior season in 2011, but he decided to forgo college for a career in the NFL. 

Korey Lindsey, Cornerback, Southern Illinois

Korey Lindsey's stock is immediately hurt by his size. He's just six feet tall and weighs only 190 pounds.

And he has suffered back-to-back hamstring injuries and NFL teams will be scared to draft a player who struggles to stay healthy. 

Any team that does draft Lindsey will enjoy his interceptions though. He is a playmaker and may not be able to start, but he can probably serve as a successful nickel back. 

Donald Buckram, Running Back, UTEP

Donald Buckram is small. He stands 5' 9" and weighs just 194 pounds. 

But he ran a 4.40 in the Scouting Combine, making him one of the fastest running backs in the league.

He missed his senior season with a knee injury, which obviously hurt his draft value. But as a junior, he rushed for 1594 yards at 6.2 yards per carry. 

Alex Wujciak, Linebacker, University of Maryland

Alex Wujciak stands 6' 3", weighs 247 pounds, and ran a 4.78 in the 40-yard dash.

He was on the preseason watch list for the Chuck Bednarik award, given annually to the nation's best defensive player. He didn't win the Chuck Bednarik Award, but he was named All-ACC for the third season in a row.

But he has had injury problems, missing parts of the 2006 and the 2008 seasons due to injury.  

Da'Rel Scott, Running Back, University of Maryland

Da'Rel Scott's stock rose drastically after he ran a 4.40 in the 40-yard dash. He is capable of breaking a game wide open with his explosive short-yardage burst and his long speed.

He has potential as a kick returner if he doesn't make it as a running back.

He played a limited role at Maryland, which will hurt his draft value. He is also coming off of a wrist injury and needs to prove that he can stay healthy. 

Rich Lapham, Offensive Tackle, Boston College

Rich Lapham is enormous. He stands 6' 8" and weighs 315 pounds. He was at 350 pounds but recently lost a good bit of weight.

He comes from a college that is known for producing quality offensive linemen, which helps Lapham's value.

But Lapham needs to stay healthy. He hurt his knee during his senior year and missed a few games. 

Greg Lloyd, Linebacker, Connecticut

No, he's not the famed Pittsburgh Steelers linebacker during the 1990s.

He's a 6' 1", 246-pound outside linebacker from Connecticut who missed almost all of his 2010 season due to a knee injury. When he did play, he was ineffective.

Injuries are obviously a concern for this outside linebacker who can also play defensive end, but when Greg Lloyd is healthy, he is a legitimate tackling machine. 

Colin Jones, Safety, TCU

Colin Jones is extremely fast. He ran a 4.40 in the Scouting Combine and possesses incredible jumping ability.

One scout compared him to Dallas Cowboys defensive back Cliff Harris, who went undrafted but appeared in six Pro Bowls in the 1970s. 

Jones is also a very good special teams player. 

Justin Trattou, Defensive End, Florida

Justin Trattou is extremely undersized for a defensive end, especially one aspiring to reach the National Football League. He stands just 6' 3" and weighs 249 pounds. 

He is pretty good at stopping the run and will collect a lot of tackles but he is not a good pass rusher. He could become a decent defensive end, but he won't be leading the league in sacks.
