There promises to be a literal firestorm of coverage as it relates to the Harbaugh brothers going up against one another in Super Bowl XLVII the weekend after this. After all, Jim and John became the first set of brothers to play one another when the San Francisco 49ers traveled to Baltimore to take on the Ravens on Thanksgiving night last season.

If you remember ESPN and the NFL Network dropping segment after segment, like a Ford Pinto drops exhaust, just imagine them doing to in preparation for a Super Bowl game.

Over here at eDraft, we will refrain (as much as humanly possible) from covering this aspect of the game. With that in mind, media just cannot help covering such a good story.

Today’s article is going to focus on their level of success heading into what promises to be one of the better Super Bowls in modern NFL history. How do they fair against other coaches who have faced off? How does their level of success compare to some of the greats the league has seen in its history?

Let’s take a gander.

Baltimore has won a total of 62 games, postseason included, in John’s first five seasons as its head coach. He has the second-most wins of any head coach in the NFL during that span, just behind Bill Belichick, who the Ravens defeated last weekend to get to the Super Bowl.

John has now led Baltimore to three conference championship games in five seasons. This doesn’t just put him Belichick company, it enables us to look further back in the long and heralded history of successful NFL coaching.

Bill Cowher led the Pittsburgh Steelers to one Super Bowl and three conference championship appearances in a four-year span, from 1994-1997. The Dallas Cowboys made three consecutive NFC Championship Game and won two Super Bowls from 1991-1993. Current Kansas City Chiefs’ head coach Andy Reid guided the Philadelphia Eagles to an unprecedented four consecutive championship games between 2001 and 2004.

Outside of those future Hall of Fame head coaches, we are looking at Bill Walsh (three championship games in four seasons with the 49ers) and Chuck Noll (five appearances in six seasons with the Pittsburgh Steelers).

That is some mighty fine company John keeps.

At his current pace, John would qualify to be among the winningest head coaches in NFL history about a quarter of the way through the 2014 football seasons. His .675 winning percentage ranks him fourth on the all-time list (eliminating away the minimum requirement of 100 games coached). This ranks him right above the likes of George Halas and Don Shula.

Not to be outdone, brother Jim has had one of the best two-year runs to begin a coaching career in the history of the NFL. Jim's 27 total wins in his first two seasons as San Francisco’s head coach ranks him behind just George Seifert and Barry Switzer on the all-time list. The only difference there being that Seifert and Switzer took over championship contenders, while Jim took over a San Francisco franchise that had won a total of 39 games in its previous seven seasons.

That is simply remarkable.

For what it is worth, not much in the grand scheme of things, Harbaugh is the winningest head coach (.750 winning percentage) in the history of the National Football League with a minimum of two seasons under his belt, just ahead of Vince Lombardi’s .740 winning percentage. Apples and oranges, my friends... I know. After all, those that sit atop that list had extended success and won multiple NFL Championships, while Jim is heading into his first Super Bowl appearance.

A better comparison is what some of the top coaches in the history of the NFL did in their first two seasons. Harbaugh in there for comparison's sake, I am in no way anointing him one of the best ever after two seasons. I might as well make a fake girlfriend up and help her contribute to eDraft. 

Overall, the Harbaugh brothers are 78-33-1 as head coaches in the National Football League. They will be taking on one another for the right to hoist the Lombardi Trophy on the first Sunday in February. But, let's make no mistake about it. Both brothers and both teams are in it for the long haul. 

After all, their success is nearly unmatched in the recent history of the NFL.
