The NCAA's new rules allowing "elite" prospects to hire agents has blindsided top officials from the NBA and USA Basketball.

The NCAA assigned responsibility to identifying which prospects qualify as "elite" to USA Basketball, but the organization doesn't have the infrastructure or interest in accepting that role.

USA Basketball prefers that the NBA make those decisions, sources said. The NBA already oversees the invitation process to the Chicago pre-draft combine and Portsmouth Invitational camps every spring. 

"We will review the NCAA's planned reforms and continue to assess, along with our Players' Association, the potential for any related NBA rules changes," NBA spokesman Tim Frank said.

John Calipari, talking about the NCAA rules changes on SportsCenter, said "None of this goes into effect until the NBA and the Players Association come up with something, and I'm hearing it won't be until 2022 so we're probably wasting our breath dealing with the ins and outs of this.
