A few things ...I don’t really get how people can defend that guy. He sounded like an asshole. I would have fired him for the statement he released about how he’s never been unethical. That was just bizarre
First off, Doyle is one of the best in the business at developing players ... period. He produced results.
Secondly, while Doyle has gotten portrayed by some as being "racist" ... that doesn't characterize him whatsoever. He could certainly be a dick ... but in the world of football, being a dick is hardly a fireable offense.
If Iowa had a system in place wherein the players could feel empowered to voice concerns about isolated offenses ... then Doyle would have received much needed feedback that some of his dick-comments could be viewed as being racially inflammatory/insensitive. With such feedback ... Doyle's comments would have remained isolated and he would have been more reflective about the things he'd say to his players (taking those few extra moments to think before you say something ... priceless).
Part of the fault, as much as anything, is actually attributable to Ferentz for having the "Iowa way" be a bit too constraining as it relates to how the players could present themselves to the rest of the world. That is on Ferentz ... Doyle was simply the enforcer. However, all the same, that aspect of the "Iowa way" contributed as much as anything to some players feeling that their racial identity/voice was being repressed. Again, had there been a better feedback mechanism in place ... Ferentz would have changed this aspect of the "Iowa way" long ago. Ferentz obviously has no desire to have his players feel as though they must "walk on eggshells."
The "shame" of the matter is that Doyle's ill-behaviors remained unchecked ... and, by not realizing how his comments were being perceived, I bet that Doyle never realized how racially charged his comments really were. Consequently, a sequence of isolated events were able to grow more into a trend. It was then that trend that got Doyle fired.
People "defend that guy" ... because this whole thing was preventable.
You're oversimplifying things by suggesting that Doyle is simply a piece of shit who should be discarded accordingly. Life isn't that simple.
