When he was in college and known as Lew Alcindor, Kareem Abdul-Jabbar and UCLA lost one game in three years (four if you count the freshman team that beat everyone it played including UCLA’s varsity).
That was a 71-69 loss to Elvin Hayes and Houston, a loss that UCLA was determined to avenge in the Final Four.
Boy did they.
The Bruins won 101-69. Here’s an extensive video of the rematch. UCLA was cutting edge at the time, an unstoppable force in college basketball.
