Hall of Fame coach Guy Lewis, who led the Houston Cougars men's basketball team to two national title games, has died at the age of 93. (0:28)

HOUSTON -- Former Houston Cougars men's basketball coach Guy V. Lewis -- best known for leading the "Phi Slama Jama" teams of the 1980s -- has died. He was 93.

Lewis died at a retirement facility in Kyle, Texas, on Thanksgiving morning surrounded by family, Houston athletic director Hunter Yurachek said Thursday.

Lewis coached the Cougars for 30 years, guiding Houston to back-to-back NCAA title games in 1983 and '84, but he never won the national championship. The Cougars lost to N.C. State in the 1983 final on Lorenzo Charles' last-second shot, one of the NCAA tournament's greatest upsets and most memorable plays.

"It feels awful," Lewis said after that game. "I've never lost a game that didn't feel that way, but this one was terrible."

Lewis, who helped lead the integration of college basketball in the South by recruiting Elvin Hayes and Don Chaney to Houston, was inducted into the Naismith Memorial Basketball Hall of Fame in 2013.

Known for plaid jackets and wringing his hands with a red polka-dot towel during games, Lewis compiled a 592-279 record at Houston, guiding the Cougars to 27 consecutive winning seasons from 1959-85. He was honored as the national coach of the year twice (1968 and `83) and led Houston to 14 NCAA tournaments and five Final Fours.

Lewis had mostly avoided the spotlight since retiring in 1986. He suffered a stroke in February 2002 and had used a wheelchair in recent years.

He was known for putting together the "Game of the Century" at the Astrodome in 1968 between Houston and UCLA. It was the first regular-season game to be broadcast on national television. Houston defeated the Bruins in front of a crowd of more than 52,000, which, at that time, was the largest to watch an indoor basketball game.

Lewis attended the introductory news conference in December 2007 for Kevin Sumlin, the first black football coach in Houston history. It was a symbolic, significant appearance because Lewis signed Houston's first two black basketball players, and some of the first in the region in Hayes and Chaney in 1964, when programs were just starting to integrate.

Hayes and Chaney led the Cougars to the program's first Final Four in 1967 but lost to Lew Alcindor's UCLA team in the semifinal game.

"Basketball in the state of Texas and throughout the South is all due to coach Guy V. Lewis," Hayes said in 2013. "He put everything on the line to step out and integrate his program. Not only that, he had vision to say: `Hey, we can play a game in the Houston Astrodome.' Not only that, he just was such a motivator and such an innovator that created so many doors for the game of basketball to grow."

Along with Hayes, Lewis also coached fellow All-Americans Hakeem Olajuwon and Clyde Drexler. The three were included on the NBA's Top 50 greatest players list in 1996. Lewis and North Carolina's Dean Smith were the only men to coach three players from that list while they were in college.

Players and CBS announcer Jim Nantz lobbied for years for Lewis to get into the Naismith Hall of Fame. When he finally received the honor in 2013, he made a rare public appearance. It was difficult for him to convey his thoughts in words in his later years because of aphasia from his strokes, so his daughter spoke on his behalf at the event to celebrate his induction.

"It's pure joy, and we're not even upset that it took so long. ... Dad is used to winning in overtime," Sherry Lewis said.

Lewis announced his retirement during the 1985-86 season, and the Cougars finished 14-14, his first non-winning season since 1958-59.

Guy Vernon Lewis II was born in Arp, a town of fewer than 1,000 residents in northeast Texas. He became a flight instructor for the U.S. Army during World War II and enrolled at the University of Houston in 1946.

He joined the basketball team, averaged 21.1 points per game and led the Cougars to the Lone Star Conference championship. By the early 1950s, he was working as an assistant coach under Alden Pasche and took over when Pasche retired in 1956.

Funeral services are pending.
