Yeah, Bill Walton won two titles in the NBA, but let's talk about his time at UCLA. As a member of the Bruins, Walton played a huge role in helping his team attain back-to-back 30-0 records and two consecutive National Championships. In fact, Walton nearly forgot what it was like to lose because from his junior year of high school to the middle of his senior year at UCLA, Walton didn't lose a single game.
