Harrell had a strong summer for AAU program California Supreme. The 2012 prospect can play both wing positions, defends, rebounds and was a big reason for Cal Supreme's success this summer.
"It was tough to choose the Ivy League over the Pac-12, ACC, A-10, MWC and WCC but I picked what me and my family thought would be the best overall choice for my future," Harrell told Scout.com.
"I have a really good relationship with the coaching staff, I loved Philadelphia, and I really like the current players on the team when I took my visit. I feel that is the best fit overall."
