Six potential replacements for outgoing Hawks general manager Billy Knight, who resigned Tuesday after six years on the job (in alphabetical order):

Chris Grant

Billy Knight's former assistant who began his career under Pete Babcock, Grant bolted for the same position in Cleveland two years ago and has since helped the Cavaliers reach the NBA Finals. Played a huge role in the Hawks' tear down and rebuild but wasn't around for the playoff triumph this season.

Billy King

King, the former general manager and architect of the Philadelphia team that made the playoff this season, spent 10 years in Philadelphia, including their 2001 run to the NBA Finals, before being fired earlier this season. Currently doing analyst work for NBA TV, he could start immediately.

Milt Newton

Newton has spent the past five years in Washington, he's currently the Wizards' vice-president of player personnel. He oversees the franchise's global scouting operation. A former player and scout, Newton is considered one of the league's finest talent evaluators.

Scott Perry

Perry is a rising star in basketball circles who played a key role in the Pistons' eight-year run as the Eastern Conference's top dog. An assistant general manager in Seattle during the regular season, he recently returned to Detroit in the same capacity after John Hammond left for Milwaukee.

Tommy Sheppard

The Wizards' vice president of basketball administration, Sheppard has spent nearly two decades working in the league in various capacities. Has spent the five seasons with the Wizards working under Ernie Grunfeld.

Steve Smith

The former Hawks great is widely regarded as one of the brightest players of his generation. Respected both on and off the floor, Smith has spent his time in the business sector as well as broadcasting (Hawks TV analyst) since his playing days ended. Knows this team inside and out.
