Kirk Ferentz and Norm Parker have turned Iowa's defense into a well-oiled machine.
Not only can Ferentz churn out NFL-caliber offensive lineman and tight ends, but with the help of defensive coordinator Parker, he has been able to produce a ton of NFL-ready talent on the other side of the ball.
In 2010, Iowa had three defensive players taken in the NFL draft.
Since 2000, Iowa has had 17 defensive players selected in the NFL Draft. Several are still terrorizing professional quarterbacks on Sundays.
Here is a list of the top 17 defenders drafted while Ferentz and Parker have been calling the shots. They are ordered from highest to lowest by where they were taken during the NFL draft.

Iwebema had a long, solid career at Iowa before being drafted by the Arizona Cardinals in 2008. After a tumor scare not long after being drafted, Iwebema has been performing well for the Cardinals defense and helped them to reach the Super Bowl in 2009.
No. 119, 2010 NFL Draft
The Miami Dolphins traded their No. 126 pick in 2010 to the Cowboys to move up for Iowa's outside linebacker A.J. Edds.
Edds is an athletic, intelligent linebacker known for his run-stuffing and pass-intercepting abilities. At 6'3" and 246 pounds, the second-team All-Big Ten selection can jam running backs and hold up tight ends.

No. 66, 2010 NFL Draft
Spievey continues the trend of successful Hawkeye cornerbacks drafted in the third round of the NFL draft.
With the No. 66 pick, the Detroit Lions added "The Glove" to their arsenal.
Spievey will join Nebraska defensive tackle Ndamukong Suh and California running back Jahvid Best in Detroit. He will likely see immediate playing time on special teams, but has an excellent chance to win a starting job at cornerback.
No. 66, 2009 NFL Draft
St. Louis Rams

No. 63, 2010 NFL Draft

His 145 tackles in 2009 ranked sixth nationally. He also has five tackles for loss, a sack, an interception, six pass break-ups, and two forced fumbles in 13 games.
Some analysts think he's slightly undersized to play middle linebacker in the NFL. The Colts didn't seem to think so.
With their first pick of the second round in the 2010 NFL Draft, the Colts went with another Hawkeye.
No. 59, 2005 NFL Draft
