Blount is a 7'0" (2.13 m) tall center and weighs 250 lb (113 kg). First signed by the Boston Celtics as a free agent on August 1, 2000, he led the team with 76 blocks that season, the most by a Celtics rookie since Kevin McHale in 1980-81.
His best season was the 2003-04 NBA season, where he emerged as a dependable center putting up 10.3 points, 7.2 rebounds, and 1.29 blocks per game in 29.3 minutes per game, and had a 28 point 21 rebound game vs. the Orlando Magic on March 1st 2004. After being rewarded with a lucrative contract in the next offseason, Blount's performance decreased. His poor defense and rebounding, along with his tendency to turn the ball over led to criticism concerning a perceived "lack of heart" on his part.
On January 26, 2006, it was announced that Blount, Ricky Davis, Marcus Banks, and Justin Reed, and two conditional second-round draft picks were traded to the Minnesota Timberwolves for Wally Szczerbiak, Michael Olowokandi and Dwayne Jones and a conditional first-round draft pick.
Despite playing the center position, Blount is more effective when utilizing his reliable mid-range jump shot than as a true post player.
