"He just thought that Butler provided him a more suitable fit," Martin's father Ken told Scout.com. "It was really close. You could say it was Butler 1 and Saint Louis 1A."
When it came down to it, the style of play and basketball brand were a big factor.
"He really liked that they were in the Big East," Martin said. "He also just thought that Butler was going to be better from a basketball perspective."
SLU made a strong run at Martin and stayed in it all the way through.
"I especially want to thank Coach [Tanner] Bronson," he said. "He was incredible and all the coaches at SLU made them a strong choice. Kelan just felt that Butler was the better choice."
