The NFL Draft is a deep pool of talent. Teams can find contributors anywhere between the first round and the subsequent pool of undrafted rookie free agents. Some huge names have been signed as undrafted free agents, many of whom were completely unknown before their respective teams gave them a shot. Here is a list of the best undrafted free agents over the last ten years.

Tony Romo, QB, Dallas Cowboys, 2003
Yes, thats right. Tony Romo was passed up by all 32 teams for each of the 7 rounds in 2003. In fact, even the distinction of Mr. Irrelevant was apparently too good for Romo. Now, $67.5 Million later, Tony Romo is the poster boy of one of the best franchises in the National Football League. From playing college ball at Eastern Illinois and being undrafted to being on the cusp of the Super Bowl, it looks like Romo did pretty well for himself. Too bad for the other 31 teams who didn't take even the tiniest chance on Romo.

Antonio Gates, TE, San Diego Chargers, 2003
In early 2003, Antonio Gates was a college athlete for Kent State. More specifically, he was a huge part of the Golden Flashes Basketball Team. Gates wanted to play football and basketball in college, but couldn't find a place that would let him do both. He eventually landed at Kent State, and led them to a MAC Basketball Championship as a Power Forward. The Chargers thought his size and demeanor suited him to be a NFL Tight End and gave him a shot as an undrafted free agent. 4 Pro Bowls later, it looks as if the Chargers made a good choice.

Willie Parker, RB, Pittsburgh Steelers, 2004
Fast Willie Parker holds the Super Bowl Record for longest run in Super Bowl history. But before his 75 yard run at Super Bowl XL, Parker was looking for a team after not getting drafted in 2004. Parker didn't have a great college career being limited by weak vision and was eventually benched in his senior year. Although he had great speed, it apparently wasn't good enough for a team to use a pick on him. Last year, Parker led the league in rushing until he got injured late in the 2007 season.

James Harrison, LB, Pittsburgh Steelers, 2002
475 pounds. The all-time Combine Record for Bench Press is held by James Harrison. A monster bench press was not enough to make James Harrison a draft pick in 2002. He played his college football at Kent State. Harrison put in his hard time on the practice squad for a couple of years before finally getting his chance on the Steelers starting squad. Last year, he made his first Pro Bowl and was selected as an All-Pro.

Undrafted Rookie Free Agent To Look Out For in 2008
DJ Hall, WR, New York Giants. Hall played his collegiate ball at Alabama. His career highlights include setting an Alabama record with five straight 100-yard games. Hall finished his last season at 'Bama with over 1000 yards receiving.
