"I talked to coach Crean after the game and it just felt right," Fischer told Scout.com. "I wanted to be part of this team."
"We had a lot to talk about," he said. "He lived in the town right next to me and one of my friends lived right by him. We have so many connections with each other. It makes everything so much easier."
"I think it's a real good relationship," he said of Crean. "I knew coach Crean back when he was at Marquette. I went to his basketball camp in the 5th grade. I got a picture with him and an autograph.
"It's funny how he actually remembers," Fischer added. "He swears he remembers me."
