He promoted his racist son to OC. I think it's fair to say. Best case scenario for you is he just didn't care and let it happen which is awful
To wrap up several hundered thousand clicks:
1. Kirk hired Doyle to be the heavy. Doyle was WAY ofer the top and not only crossed the line of human decency he jumped over it on a regular basis. Too many times to count.
2. Doyle did get results so Kirk allowed the mistreatment of human beings. There appears to a despearancy of mistreatment of black players. Because of the results Kirk knowingly never held Doyle accountable for his methods.
3. Doyle becomes untouchable over the years, young coaches now want to emulate Doyle. Enter BF. Brian now want to be like Doyle and tensions rise. Brian has a couple public episodes. Kirk is required to respond because the cameras were on and public got a glimps of the iowa way.
4. Former players complain, more come out on Doyle, Brian and Kirk, Kirk asks Doyle to step down, insulating Kirk and other coaches.
5. More investigations are in play, Kirk is again in damage control trying to save legacy and a potential statue in kirks honor.
Conclusion
a. Doyle clearly a significant problem - Result Fired due to public outcry.
b. Kirk clearly knew of and supported Doyle's methods - Result TBD
c. Brian clearly wanted to be like Doyle, used his methods - Result TBD
We'll see how this ends but I know If I had this situation with my business, I'd been fired months ago with no need for an investigation.
