"My main reason is I'll be playing for a Hall of Famer who has a tremendous staff and I'm going to be with a great group of guys," Simon said. "I feel like I can be myself there and accomplish a lot."
"They really sold me on their workouts and how they train their guys and then showed clips of what they do in workouts and then how it translates into games," he added. "Their style of play fits me."
Coming out of high school, Simon, a 6-foot-5 lead guard, was ranked No. 27 overall, but Simon played just 7.5 minutes a game during his freshman season at Arizona, averaging 2.3 points and 1.2 rebounds per game.
Simon opted to transfer on March 28th. He will sit out next season, per NCAA rules, and then will have three years of eligibility remaining.
"I'm going to get better in that year sitting out," he said. "I'm going to work hard and prepare for next year."
Simon took a visit to St. John's this past weekend. He previously visited Oklahoma State the weekend of April 9th. Miami, Providence, New Mexico and others were also involved in his recruitment.
Simon is the second transfer to opt for St. John's in as many days. Michigan State transfer Marvin Clark committed to the Red Storm on Thursday. St. John's will also add top 100 point guard Shamorie Ponds and four-star German native Richard Freudenberg to their roster next season.
"There's a lot of young guys, me being one of them and I'm going to mature, learn, get better and when it's time to play I'm gonna help St. John's make some noise in the Big East and get to the tournament," Simon said.null
