So say Riley comes in without his trusted assistants, then what? You are starting over trying to gain the trust with your coaches and your players. That would be an incredibly difficult situation for someone to be in while also being expected to win (which I know he didn't in year 1 anyway). So he brought in some trusted coaches to try and help change the culture and get the program headed in the direction he wanted it to go. Now after having gotten the culture going in the right direction, he has been able to truly evaluate his assistants. And I think he saw they weren't getting it done, but they did help with the transition.
