The Iowa Hawkeyes football staff has undergone major revisions over the last two years.
Only three coaches remain who were on the staff at the end of the 2011 season, and all of those coaches either have a completely different position within the staff or have new or different responsibilities.
In the end, the face of a program and all of its decisions come down to the head coach. However, a head coach is only as good as his staff.
Former Iowa head coach Hayden Fry knew that. That's why his coaching staff featured coordinators and coaches who eventually went on to great things, as detailed by CoachingRoots.com.
Current head coach Kirk Ferentz doesn't have nearly as impressive a lineage, but Ferentz apparently looks for different qualities than Fry did in his staff.
The following will look at the Iowa Hawkeyes football staff that will be in charge during the 2013 season.
As with last week's article, which detailed coaches who had recently moved on, the criteria for assessing the coach's effectiveness will concern recruiting, attrition, discipline and player development.
In the modern world where everybody knows everything about everyone, recruiting is fairly open. Consequently, thanks to Rivals, which lists which coach recruited which player, fans know how effective the coaches have been. This element of the criteria does not concern itself with how the recruited player developed, only how successful the coach was on the recruiting front.
Attrition and discipline are tougher to measure. In effect, there are no hard numbers to gauge them. There is only the eye test and the depth of my memory.
Development will concern itself with how players in a position group developed under a specific coach. Therefore, a coach who led a 5-star player into the NFL draft will receive credit, but a coach who has consistently done the same with 2-star players will receive even more credit.
There are, of course, other measures of a coach's effectiveness, such as game planning and in-game adjustments. Nonetheless, those are elements of the game about which outsiders couldn't make a reasonable judgment.
Finally, the three new coaches haven't done anything as Hawkeyes. Consequently, the only criteria will be what they seem to bring to the Hawks.
