SANTA CLARA, Calif. (AP) - Jim Harbaugh's new coaching staff is nearly in place and he is in a full-on, head-down planning mode. His normal schedule: a half day spent on draft evaluation and the other half preparing offensive and defensive schemes.

There's not much else Harbaugh can do at the moment as a first-year NFL coach heading into an offseason of uncertainty with the league's unsettled labor situation.

Harbaugh announced two more hires Friday and the retention of four coaches already on San Francisco's staff. Keeping their jobs from fired coach Mike Singletary's staff are offensive line coach Mike Solari, running backs coach Tom Rathman, defensive line coach Jim Tomsula and assistant offensive line coach Ray Brown.
