How’s this for being upwardly mobile:

Lawrence Frank, who was last seen heading for the unemployment line last December after the Nets started 0-16, has agreed to be the assistant coach on a team that came within one victory of the NBA title.

The former Nets coach has agreed to assist Doc Rivers and the Boston Celtics for just one season, essentially filling the role occupied by Tom Thibodeau, who left Rivers’ staff to to take the Chicago Bulls job.

“I think it’s a good situation for me – I wanted to get back and coach, and I didn’t want to sit and wait, and you can’t ask for a better situation or a better organization,” Frank said.
