May 21, 2006 - LeBron James fired in 10 of his 15 field goal attempts during the first half of his team's elimination game against the Detroit Pistons. Unfortunately, James would miss his first seven attempts of the second half, connecting on just 1-9 in the third and fourth quarter combined.
James' teammates, meanwhile, combined to shoot 9-41 (21.9%) from the field over the course of the entire ballgame, ultimately leading to Cleveland's playoff elimination.
