It would appear as though "Sir" Don Nelson's days could be numbered in Oakland.

After beating the Knicks 121-107 on Friday night, Nelson stands only 21 wins shy of becoming the NBA's all-time winningest coach. But his insistence on alienating and humiliating his best players -- which continued at Madison Square Garden even in victory -- could soon lead to a coaching change, a high-level coaching source told CBSSports.com.

With no realistic trade scenarios emerging for Stephen Jackson -- and with the team's other miserable star, Monta Ellis, wanting out, too -- Nelson's last option to keep the team from blowing up already is under consideration. Nelson, 69, would assume a consultant role, with top assistant Keith Smart taking over as head coach.

"It could happen by next week," the source said.
