edit-merged, sorry Kneepad, missed your post.DALLAS -- Don Nelson, the second-winningest coach in NBA history, resigned as coach of the Dallas Mavericks on Saturday and turned the team over to protege Avery Johnson.
"I see a little slippage as a team," Nelson said. "The team is just responding better to Avery at this point."
The 64-year-old Nelson also had the title of general manager, but most of those duties were done by his son, Donnie, the team's president of basketball operations. The elder Nelson will stay with the team as a consultant.
"Nellie has earned the right to approach this any way he wants," team owner Mark Cuban said. "I just wanted to be supportive of any direction he wants to go."
Cuban told ESPN.com's Marc Stein that Nelson resigned Saturday "for family and other reasons."
