The 6-foot-6 ½ Rush, a Kansas City native, prepped at Durham (N.C.) Mount Zion last season. A big time athlete, who is an adept slasher and scorer, gives the Jayhawks one of the elite recruiting classes in college basketball.
KU coach Bill Self, who learned of the news on Friday, was clearly enthusiastic about the addition of Rush.
"We're obviously excited," Self told Scout.com. "It's not very often in August that you can recruit somebody of his talent and have him play for you that year. It's a very unique situation and one that we started pursuing after we heard that he might have an interest in Kansas.
"Our people are persistent and did everything they could to work with the clearinghouse. He has been cleared and I think it makes us a better team right off the bat."
Rush, rated the No. 4 small forward in the Class of 2005 (No. 15 prospect overall), gives KU 3 of the top 5 small forwards from the class. Julian Wright was the country's top small forward and Micah Downs was No. 5.
"Depending on how well he adjusts to our style and guarding and buying in – which we feel like there won't be any issues – we feel like he'll have a chance to be one of our leading scorers," Self said Friday afternoon.
