I have never heard of a school not fire a poorly performing football coach because they felt the players were not up to snuff? If you recruit players who don't perform it will lead to poor performance on the field. I don't believe players were the problem...the choice of players lead to his criticism and bad run the last 5 years. As well as play calling, game management and in game strategy.....
Northwestern had a horrible season last year - but that is largely attributable to injuries. Through the prior 2 years, not only did they suffer from untimely injury issues - but also the whole player-union-movement at Northwestern served as a bit of a distraction. These aforementioned factors contributed to players being the problem ... however unfair that allegation may seem.
Without the benefit of context, it would be easy to throw Fitzy under the bus. However much I dislike the guy, without a doubt, he's a great "fit" at Northwestern AND he's a talented coach.
As it relates to Iowa, severe attrition issues had depleted the squad through the past 5 years or so. As it related to the defensive line ... Coach Kaz was pretty obvious contributor. Running back was another position that got hit - although the causes there were less obvious. Some was probably due to Erb ... although injuries and off-field issues definitely contributed as well. Heck, a portion of the RB issue is probably due to the fact that it is a high-profile position ... and players at that position don't always share Ferentz's blue-collar philosophy.
In addition to attrition issues, the coaching changes Iowa had were no less significant. I would attribute A LOT of the issues that the Hawks have experienced over the past several years as being influenced by these factors alone.
The fascinating question I keep asking myself is this ... are those issues now behind us?
Then I encourage to parse the Iowa roster as obsessively as I do (actually don't ... it's weird) - you'll find that our team is surprisingly YOUNG. There is plenty of talent on roster AND the success of this year will likely be having them embracing the formula of commitment and unity that helped to cultivate the winning culture that we're now observing.
Furthermore, look at Iowa's next few recruiting classes ... there's talent there too. Heck, just imagine what the D-line could like with guys like Hesse, Lattimore, and Epenesa on it!
I'm reminded of how I felt about the promise of program back when we enjoyed the run from '02 to '04. The difference here being that the culture of entitlement that crept in ... along with Norm's declining health are factors that ended that first promising run. I'm not sure I see obvious stumbling blocks that would undermine the present momentum of the program.
