"Today I committed to Indiana," Robinson said. "When I went on the visit I just fell in love with the campus. Me and coach (Tom) Crean hit it off. He told me his plan and I agreed with it and then the additional benefit was coach (Kenny) Johnson being there and we are really close."
The relationship Robinson had with Johnson, who previously coached the rising senior at Paul VI, was a big part of the decision.
"Me and coach Johnson could be brothers," Robinson said. "He was the one that recruited me to Paul VI in 8th grade. Ever since then we have been close. I just trust him 100 percent."
The four-star prospect is rated 52nd in Scout.com's 2013 recruiting class, coming in as the 9th rated shooting guard.
He's excited about his future in Indiana.
"Hoosier Nation," Robinson said, "I love it."
