"We are challenged by change, but excited to attack the future with great purpose," Carroll said in a statement. "I want to thank both Tom and Darrell for their role in helping take this program to a championship level. I will always be grateful for the opportunity to coach and compete alongside these great men."
"We all have to keep changing and growing together. That's why I always come back to compete, you know," Carroll said. "Keep competing to find a way to make sense and help a guy and pushing him to have success. Then we will do what we can do. Sometimes we do it better than others. Sometimes we shock the heck out of this, with all kinds of things that happen."
