Of far greater certainty is the status of coach Kurt Rambis, who appears to be on his way out after only two seasons. Though management won't make a final decision until the season is over, sources say there is significant push from within to make a coaching change.

With a young roster clearly lacking in veteran leadership, some members of the Minnesota brain trust believe the team needs a more vocal, energetic coach on the sideline.
