The 2012 Iowa Hawkeyes went 4-8. This will be the first Hawkeye team to stay home for the bowl season since 2007, and it will be the first group that failed to qualify for a bowl since 2000.
Regardless what the stats say, this was probably the worst Iowa defense since 2000, and it was the worst Kirk Ferentz-era offense.
Furthermore, 2012 was on the back of two subpar performances, both of which saw the Hawkeyes go 7-5.
The team was, in fairness, young, but it wasn't so young as to merit losing to Iowa State, Central Michigan, Indiana and Purdue, three of which were home games and all of which were against mediocre or worse squads.
Moving ahead, there are changes and adjustments Kirk Ferentz can make, and, in some cases, has to make if he expects his program to flourish in an increasingly competitive Big Ten.
That said, Ferentz is not going to change to a spread offense, and he's not going to open up the defense as though he's Nick Saban. The Iowa offensive scheme is not going to focus on a dual-threat quarterback, and the defense is not going to change to a 4-2-5 base.
In short, the changes suggested on the following slides only work within the realm of Kirk Ferentz's reality.
