Alan Henderson (born December 2, 1972 in Morgantown, West Virginia) was obtained by the Mavericks in a trade, along with Jason Terry, from the Atlanta Hawks in return for Antoine Walker and Tony Delk.
Henderson attended Indiana University where, as a freshman, he averaged 11.6 points, led the team in rebounding with 7.2 rpg, was voted All-Big 10 and helped lead the Hoosiers to the NCAA Final Four.
His junior year he led the Big 10 in rebounding and was All-Big 10 and Honorable Mention All-American in both his final two years at Indiana. He led the Hoosiers in scoring as a senior at 23.5 ppg and played for Team U.S.A. in the 1994 Goodwill Games. Henderson graduated from Indiana with a degree in biology and was accepted into the university's medical school. On the court he was the only player in Indiana history to complete their career in the school's all-time top 5 in scoring, rebounding, blocks and steals.
Drafted by the Atlanta Hawks in the firsr round of the 1995 NBA draft, Henderson saw action in 79 games his rookie season averaging 6.4 points, 4.5 rebounds and was second on the team in blocked shots. His sophomore campaign was limited to only 30 games as he missed almost 50 games with acute viral pancreatitis. He came back strong, however, the next season posting a career-best 14.3 points in 69 games while being voted the NBA's Most Improved Player award.
Averaging 12.5 points in 1998-1999, the 6'9 forward helped the Hawks to the playoffs for the fourth consecutive season. It would also be his final playoff appearance with Atlanta although he played another five seasons with the team. Henderson had averaged of 13.3 points and 10.5 points over the next two seasons and posted a career-best 7.0 rebounds in '99-'00.
The 2001-2002 season was shortened by a sore right knee that cost Henderson 56 games. Although he came back the next year to play in all 82 of Atlanta's games, he was limited to only 4.8 ppg. The injury bug was at it's worst in 2003-2004 as, in what would turn out to be his final season with the Hawks, Henderson only saw action in 6 games due to back problems.
During the offseason, he was traded to Dallas where, healthy again, he played in 78 games averaging 3.5 points and 4.5 rebounds in 15.4 minutes of action. On February 24, 2005 Dallas traded Henderson and Calvin Booth to the Milwaukee Bucks for forward Keith Van Horn. The Bucks released him the next day and on March 1 he re-signed with the Mavs. He returned to help Dallas to the playoffs where in nine games he averaged 2.0 points and 1.9 rebounds in 10.0 minutes.
His final two NBA seasons were spent with Cleveland and Philadelphia respectively where he has scoring averages of only 2.5 points and 3.1 points. Henderson retired after the 2006-2007 season.
In a very special honor, Henderson was named in 2001 as one of the Top 50 Players in Indiana state basketball history.
