Just because the Baltimore Ravens and San Francisco 49ers earned berths in Super Bowl XLVII, they are not impervious to flaws.
Every team in the NFL has weaknesses, and those of the teams competing for the Vince Lombardi Trophy receive extensive transparency. It's simply a matter of the opponent having two weeks to prepare for the biggest game of the season.
Include the Ravens and 49ers previously meeting on Thanksgiving in 2011, and these teams know one another quite well. Not to mention the head coaches, John and Jim Harbaugh, are brothers.
Neither Baltimore nor San Francisco has drastically changed since last season's matchup either.
Colin Kaepernick taking over for Alex Smith is the most notable change, but each team's philosophy of running the rock, playing defense and getting physical at the line of scrimmage hasn't altered. Despite being located across the country from one another, Baltimore and San Francisco possess similar approaches.
That said, the weaknesses between them will garner significant attention on Super Sunday.
