Harbaugh surprised his staff is still intact

There is one head coaching vacancy in the NFL -- the Cleveland Browns'.

If the Browns do not hire a San Francisco assistant (the job appears to be wide open but no 49ers' assistants have been connected to the job as of yet), that means Jim Harbaugh's key assistants will return for the 2014 season. Earlier this month, Harbaugh said he thought at least one assistant would get an NFL head coaching job.

Offensive coordinator Greg Roman and defensive line coach Jim Tomsula interviewed with Minnesota. Roman and defensive coordinator Vic Fangio were on the Redskins' interview list initially.

Harbaugh said Friday "it was hard to believe" none of his coaches have gotten job. He said many of his assistants are better coaches than he is.

"It will happen," Harbaugh said. "There will be a smart club."
