Currently Sund is a "Basketball GM and Scouting" instructor for the online sports-career training school Sports Management Worldwide, founded and run by Dr. Lynn Lashbrook.

Sund holds a bachelor's degree in political science from Northwestern University where he was a two-sport athlete, twice named academic All-Big Ten on the basketball squad, while also seeing action as a tight end and wide receiver on the football team.

[1] The expansion Dallas Mavericks hired him in 1979 at 28 years of age, making him the youngest general manager in the NBA's history.

[citation needed] He helped assemble the first ever Mavericks roster, and for the remainder of his multiple-year tenure around the organization, brought in Brad Davis, Rolando Blackman, Mark Aguirre and others.

[1] He moved on to the Detroit Pistons in 1995-96, a roller coaster five seasons at the helm of a talented team holding a young Grant Hill.

One of the most notable trades during his tenure was the 1997 deal of Otis Thorpe to the Vancouver Grizzlies for a protected future 1st round pick.

In the summer of 2011, the Hawks only draft pick, in the second round, was used on Keith Benson, who didn't make the team during the December training camp.

However, Sund also re-signed Collins, and added Tracy McGrady, Willie Green, Jannero Pargo, Vladimir Radmanović, Jerry Stackhouse, and Eric Dampier, all at veterans minimums.

Signing that many veteran minimum contracts pushed the Hawks into the luxury tax, although McGrady, Green, and Pargo had productive seasons.

Childress also came back from Greece, and was signed-and-traded to Phoenix for a trade exception (not used) and a second-round draft pick (sold for cash to pay the luxury tax).
