There are three things that have stopped Iowa from taking it to the next level over the last 8 years. 1)Iowa basically spent 2012-2014 starting a FB as their featured runner. Most of this had to do with attrition at the position whether it was transfers, injuries, or being players being dismissed from the team. It shouldn’t be hard to find at least one capable Power 5 RB and Iowa’s bad luck over a 3-5 year time frame was incredible. 2) Iowa’s OL’s always seem to have had a couple of good pieces, but the units overall have been more along the lines of average to above average. Even in 2015 when the Ol paved the way for a pair of 1,000 rushers, they struggled in pass protection. 3) Much like the OL, the DL usually has a solid individual, but they often haven the had two difference makers simultaneously up front.
