Here are some quotes from the UW's official announcement:
"Leaving Wisconsin is the hardest decision I have had to make in my professional career," said Koch. "I am leaving a great program, with great staff and players. I am excited for the opportunity to be a head coach and it will be a good move for my entire family.""Dan has an opportunity to move on and be a head coach and take his family to a prep school," said Wisconsin head coach Mark Johnson. "He has been a great asset for us the past seven years. He has played a major role in building our program and we know he will do great things at Shattuck-St. Mary’s. We wish him the best of luck and we will miss him."
"Mark has been a mentor for me the past seven years and I appreciate everything he has done for me and I have learned from him," Koch said. "He is not only one of the best hockey minds, but he has taught me so much about life as well."
