McKeown worked as an assistant coach at the University of Oklahoma from 1983 through 1986, where he interacted with many big names in women's college basketball including Budke.
"We spent a lot of time on the road with recruiting. He was really just a class-A person," McKeown said.
Budke was the head coach of OSU since 2005. Before that, he coached at Louisiana Tech, first as an assistant and later as a head coach. Serna had been at OSU for seven years.
"They gave their lives to women's basketball," McKeown said.
