Harbaugh deserves a lot of credit for the job he has done integrating a new coaching staff with a veteran team, and finding success with an inexperienced player at the most critical position on the team.
Can he take this squad deep into the playoffs?
Only time will tell. But with the strengths of this team lying in the areas you typically associate with winning playoff football (i.e. running the ball, great defense), I wouldn't bet against it.
