Herb Simon, one of the new owners of the Indiana Pacers, said in Indianapolis he will "make every effort" to sign collegiate basketball star Ralph Sampson if the Pacers win a coin flip with Houston next month and get the National Basketball Association draft rights to the University of Virginia athlete.

"We are committed to getting the best possible players on a prudent basis," said Simon after announcing he and his brother, Mel, had purchased the team from Californians Sam Nassi and Frank Mariani.

Mel Simon was listed in Forbes magazine as one of the 400 richest men in America, with an estimated worth of $500 million . . .

In Seattle, Sam Schulman, the angry majority owner of the SuperSonics, said "radical changes" are in line for his NBA team, which departed the playoffs with two straight losses in the first round to Portland. But he said Lenny Wilkens will return as coach next season . . .

In Kansas City, Mayor Richard L. Berkley said he is asking a city council committee to study the Kemper Arena lease situation of the Kansas City Kings, who have fallen behind in their rent. Berkley is unconvinced the lease should be terminated, as had been advised by the city auditor.
