The NCAA decision to allow Nevada-Las Vegas to defend its national championship was based on an unusual set of circumstances that cannot be compared to any other school, the NCAA executive director says.

The NCAA reversal in the UNLV case has been criticized by several schools, particularly Kansas, which was not allowed to defend its national championship in 1989."People don't realize UNLV served an institutional penalty 13 years ago," Dick Schultz said Monday. "This is not a normal infractions case. It's really a show-cause situation, and it's complicated by the permanent injunction."

The NCAA Committee on Infractions ruled last week that UNLV, ranked No. 1, can participate in this season's NCAA tournament. Instead, the NCAA gave UNLV a choice of alternative penalties. The school chose to sit out the 1992 tournament and be kept off live TV that season.

Kansas coach Roy Williams and some of his players criticized the NCAA last week for giving UNLV the option.

"I sure wish they'd given us a multiple choice penalty," Williams said.

On Monday, Schultz said the critics of the NCAA decision do not understand the situation.

"It's not that UNLV is being given an opportunity to play because they are the defending champions. That has nothing to do with it. UNLV has already served a penalty for this."
