Joe Flacco wasn't the only high-profile rookie on the Baltimore Ravens in 2008. John Harbaugh was also in his first year as an NFL head coach, and it appeared, based on the Ravens' 5-11 record in 2007, that he had a big job ahead of him. It's hard to imagine, however, that anyone would have expected this team to be playing at the level they are entering the playoffs.
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.
