Houston lost in both NCAA Final games in which Lewis coached, despite his "Phi Slama Jama" teams featuring superstars Clyde Drexler and Hakeem Olajuwon. In 1983, Houston lost in a dramatic title game to the North Carolina State Wolfpack on a last-second dunk by Lorenzo Charles. The Cougars lost in the 1984 NCAA Final to the Georgetown Hoyas, led by Patrick Ewing. Lewis retired from coaching in 1986 at number 20 in all-time NCAA Division I victories, his 592–279 record giving him a .680 career winning percentage.
