LeBron James said the Los Angeles Lakers cannot afford to make any mistakes when they face off against Stephen Curry and the Golden State Warriors in their blockbuster playoff series opener on Tuesday. James and Curry go head-to-head in a playoff series for the first time in five years on Tuesday when the Lakers and the Warriors meet in game one of the Western Conference semifinals in San Francisco. It is the latest heavyweight showdown between two of the greatest basketball players in history, who faced each other in the NBA finals for four straight years between 2015-2018.
