A big part of Kirk Ferentz's legacy at Iowa, and the secret to his success, has been the development of underrated prospects into All-Big Ten performers and NFL Draft picks. In this "Ferentz at 20" feature, we take a look back at the best two-star prospects that Iowa has signed during Ferentz's tenure and the success that they achieved on the field. For the purposes of this article, we are looking at scholarship recruits only. We will be doing a separate feature on the top walk-ons of the Ferentz era. With that in mind, let's dive in.

While Bob Sanders pre-dates the current version of Rivals, he was a two-star on the previous site as a lightly recruited defensive back out of Erie, PA in 2000. It was Kirk Ferentz's mentor, Joe Moore, that reached out to his former pupil and recommended the Hawkeyes offer, saying Sanders could help them on special teams if nothing else. Sanders, of course, did that and a whole lot more during his time at Iowa, earning first team All-Big Ten honors three times. After college, Sanders was a second round pick by the Indianapolis Colts in the 2004 NFL Draft. There, he won a Super Bowl and was named NFL Defensive Player of the Year in 2007.

A lightly recruited 225-pound in-state tight end in the Class of 1999, Robert Gallery grew into a 320-pound All-American offensive lineman at Iowa. Like Sanders, Gallery played a key role in Iowa's turnaround early on in the Ferentz era, holding down the left tackle position and setting the tone upfront on offense. A two-time first team All-Big Ten selection, Gallery won the Outland Trophy as the nation's top lineman and was a consensus first team All-American as a senior in 2003. In the 2004 NFL Draft, the Oakland Raiders selected the Masonville native in the first round at No. 2 overall, the highest draft pick of the Ferentz era.

On the advice of Reese Morgan, Kirk Ferentz offered a late scholarship to Josey Jewell in 2013 when his other options were UNI and Luther at the time. Jewell quickly proved it was worth the risk as he worked his way into the lineup at middle linebacker as a redshirt freshman and never looked back, finishing his career with 43 starts and his portrait on the wall as a first team consensus All-American in 2017. Jewell is also the only player in the Ferentz era to be voted a three-time team captain. This past spring, the Denver Broncos selected the Decorah native in the fourth round of the NFL Draft.
