Watch: Ravens HC John Harbaugh surprises brother, Jim, at CFP title game

Brothers John and Jim Harbaugh are the definition of football is family. 

John Harbaugh, the head coach of the Baltimore Ravens, traveled to Houston, the site of the College Football Playoff national championship game, with some of his coaching staff to support his brother, Michigan Wolverines head coach Jim Harbaugh.

However, John Harbaugh and the Ravens brass reportedly faced weather delays on the way to the game as their plane got diverted to Austin, Texas.

But that didn't stop John Harbaugh from supporting his brother. He showed up on the sideline midway through the second quarter and the two shared a hug.

The two brothers have a chance to do something special this year.

Jim Harbaugh can lead the Wolverines to their first national championship since 1997 on Monday night with a win against the Washington Huskies. 

While John Harbaugh can lead the Ravens, who boast the NFL's best record (13-4) as the No. 1 seed in the AFC, to their first Super Bowl since 2013.

The two have molded their teams in similar ways as well with a focus on running the football and playing great defense. 

Baltimore is averaging 156.5 rush yards per game and is allowing the sixth fewest total yards per game (301.4) in the NFL. 

Michigan is averaging 159.5 rush yards per game and is allowing the second fewest total yards per game (239.7) in college football.

The Harbaugh brothers clearly know what it takes to build and lead championship-caliber teams. But they have proven it's a lot more fun with someone by your side.
