Yes, if you blitz you might get burned, but the same is true if you don't. Remember that last four seconds of the PSU game? Conservative defense. No blitz. No risk. No reward.
This is a great example of why so many of the criticisms of Ferentz and this staff are mocked by those labeled "apologists."
Iowa did blitz on the last play of the PSU game. McSorley then threw the ball within 3 seconds and completed a difficult pass.
So many of the Ferentz-haters simply cannot be taken seriously because they seem to believe that all it takes to be a great coach is to just be ultra-aggressive (i.e., blitz constantly, throw the ball deep). In this case, it appears as though the thought process was that "bad result" = "not aggressive enough" as if it's that simple.
Ferentz certainly has earned his share of criticism over the years. We've seen a number of mismanaged clock situations, reluctance to pull starting players (e.g., Herb Grigsby, Jake Christensen), and too many losses when we were double-digit favorites. Some of these issues should be easier to fix than others, and sometimes the coaches do everything they can to put players in position to succeed, but the players simply don't execute.
Ferentz is not the best coach in the country or in the conference, but he is still one of the better coaches around and has had 3 different seasons where Iowa was in the national championship picture in November. A coach doesn't have as much success as Ferentz has had by luck, and those that portray Ferentz and his staff as idiots simply do not have the mental maturity to make a reasonable assessment.
